OP:
Sunday I am completly replacing the stock exhaust from the block back so I figured I'd start a post showing what we do and the finished results. I'm going with:

DC Ceramic 4-2-1 Headers
Magnaflow High-Flow Cat
APEXi WS2 Catback

I'll post pictures and details once it's done with help from Tim and Dom.

I'll make sure to bring my camera so we can both take pics.  Can't wait to tackle this project on Sunday.

Sounds like a nice Sunday project. You're gonna love the difference.

So after three and a half hours on a Sunday afternoon, tons of PB Blaster, grunting and groaning, a snow squall, a few swears and Tim's delicious homemade pico de gallo, I have a completely new performance exhaust from the headers back.

Here are the box of goodies. The APEXi came straight from Japan a few days ago and the headers were replace by the awesome DC rep (due to the quality issue I reported in another thread).

These are all the parts laid out for mock up.

We decided it was best to drop the entire exhaust from the flex pipe back. There was so much corrosion from 130k miles and New England winters

The difference is amazing! It feels like I have stopped driving through mud I didn't even know I was in. It's sound nice and throaty and when you open it up it gets aggressive but with mid range tone. Nothing tinny about it. It won't get cop attention unless I'm jamming on the throttle. I highly recommend APEXi!

Thanks to Tim and Dom for all the help again!!

Dope!!  I have to post my pics when I have a spare moment.  It was definitely fun doing the install yesterday, but I'm pretty sure that the moisture and quick temperature drop is what gave me this cold.  Good times though.

Sound clips!!!

+1 cause I HATE my WSll. but that might be cause I still have a stock cat and header. does the idle sound farty right at the muffler? mine sounds really airy [nicer word for farty i guess] at part throttle. only time I like it is at WOT

I don't think it sounts airy or farty. It's a nice low resonating tone. (I idle at aprox 800) Almost a tone that you feel in your chest.

I'm addicted to the tone change as it opens up around 3500 and unfortunatly has me going faster down certian roads than I probably should be!!

I'll put up sound/video clips as soon as I can.

please do. Your description has left me teary eyed =[

nice - looks much improved from stock.  im sure you can feel it breathing a lot better.  get some sound clips up!

Funny thing is that we thought about that.  Since all 3 of us doing the install had recording equipment (at least I think Keith does), we considered running a long cable from Dom's studio out to where we were working.  I may bring my laptop, DAW, and stereo mic to work one day to get a few sound clips.

I'd be in your debt forever Tim

I'm kinda torn between two resonators (both from vibrant but ones shorter/fatter and the other is the bottle style)

http://vibrantperformance.com/catalog/p ... cts_id=291 (http://vibrantperformance.com/catalog/product_info.php?cPath=1021_1033_1054&products_id=291)

http://vibrantperformance.com/catalog/p ... ucts_id=46 (http://vibrantperformance.com/catalog/product_info.php?cPath=1021_1033_1055&products_id=46)



Which one would sound better (i know this is a very vague question until I actually get one). Honestly I don't know much about which resonator would work better (sound wise) with my set-up but from my understanding shorter/fatter would do more of a job of sound dampening [could be wrong; HORRIBLY wrong haha]


What is everyone's opinion? If anyone has any other suggestion feel free to post it (never really liked the idea of having a resonator on an aftermarket/custom exhaust but this high-end rasp/backfire is aggravating me)

It really depends.  I don't think that a shorter fatter resonator will make it quieter though.

The shape of resonators generally doesn't make a differance in sound dampening, its more the internal composition of them.

Hmm, I was thinking that also but wouldn't the amount of composition materiel affect the sound?

Obviously, a larger resonator with equal internal properties will be quieter than a smaller resonator.  Using quick and dirty math, the oval resonator has a volume of about 300 ci, while the round resonator has a volume of about 250 ci.  Also, the oval resonator is labled as an "Ultra Quiet" resonator, while the round one is just a "Bottle Style" resonator.  That should clue you into a little more about their sound characteristics.

hey does your car throw codes when you swapped out the oem cat for that one

whats the part number for the maggi high flow cat you used

ive got the same setup minus the hi flo cat. If anyone is on the fence about doing this i highly recomend it. I want to do the dual setup.

Same question :D

No codes when he did the swap.

Do you have a part number by any chance? Or do the codes appear later on for some reason?

Nice install! I'm betting it sounds just as good as it looks. Using the cement blocks there for extra security incase a jack failed?

I believe the Magnaflow part number is 27405 (http://www.car-sound.com/02product/displaydirectfit01.asp?catalogid=15283&directfit=27405).  It's listed as an 05-07 part, but there's no reason why it won't fit an 03-04.  I don't really understand your second question though.  There were no codes after we did the swap (and replaced his bad secondary O2 sensor) that I know of.  I believe everything has been just fine since the install.



It sounds awesome.  Definitely a good upgrade.  You are correct about the cinder blocks Sam.  We used jack stands at all 4 jack points, the cinder blocks at the front wheels, and had a floor jack at the rear.  You can never be too safe.

yup! at first i saw the blocks and was like WTF ARE THEY DOING!!! lol, then i noticed the jacks

Hmm that is an expensive site you got there... in Google shopping there is a bunch around 140... Thanks a bunch for the part number though... and my second question was simply that if you put the cat on there will the codes appear later, because i remember Skippy mentioning somewhere that people always end up throwing codes... But it's good to know that this one does not :D

That site has high prices because it's the manufacturer's site, so MSRP is listed.  That's the actual Magnaflow product page.  As far as the CEL, you will be fine with this cat.  I have a 5400 series universal cat and I threw codes when I installed it.  That was resolved with $5.00 in parts.

i put the defoulers on before i started the car and never threw a code .... i also have the 5400 series universal cat...2.25 in/out

With my new hi-flo cat the only thing left is the remaining exhaust.  I like the quietness of the stock exhaust but would not mind a little more sound. I really like how the newer si's sound.  I'm thinking about trying to put an 06 si exhaust on my coupe from the cat back.  What do you guys think? Most aftermarket exhausts I hear are way to "weed-wacker" sounding or loud.

You can try it if you want.  You may want to consider a TSX exhaust too.

tell us how it sounds when you do it. I am going to get dual TL mufflers on my i4 accord soon.

keep us posted.i am also interested in this, as i was thinking about the si muffler too. i just dont want things getting any louder

Besides the muffler would I need whats labeled #8 "Pipe B" ? Can anyone tell if that part includes the resonator?

(http://www.hondaautomotiveparts.com/auto/jsp/mws/catimgs/14SVA6_B0201.gif)

Your best bet is to just get the muffler and have a shop weld it on to your existing exhaust system.  I highly doubt it will do much for performance though.

Well, I'm not really doing this for performance gains....it would be for a slightly more aggressive exhaust note.  Do you think just the muffler would change the sound or would I need the mid-pipe too?

A muffler change may make a slight difference, but it will probably be barely noticeable. You may want to consider having your "pre-muffler" removed too.

I dont think just putting the muffler on will change it that much. Remember a lot of time the exhaust note of cars has more to do with the engine than exhaust. For instance just slapping a G35 exhaust on a 6 cyl Accord will not achieve the same exhaust note.

thats true but the Si motor is a K series with vtec. So I am sure that even if it is not 100% close it should somehow sound similar. Like I suggest you just get the muffler and get a magnaflow resonator.

*kinda off topic* For me I am just doing it for the looks. Those TL muffler looks bad ass on the accord. so 2.25in piping 18in resonator, y pipe and those TL muffler. Like I can't complain I am getting both TL muffler with tips for 100 and they are ready 2.25in

It's a K-series but very different. We'll see...

Well think of it this way, we have two valves open at 2200 rpms (at similar lifts) and so do k20z3s. until they hit vtec a little above 5k rpms. So other than displacement they should sound very similar, and likely you wont get that high pitched weed wacker sound because we dont have the race lobe like they do. Im eager to see how this works

I am looking to put my first exhaust on my car, and I would really like some opinions, and help, I have narrowed it down to an A'PEXi exhaust or a Tanabe one, but I want to know what people who actually put on on an accord say.  And I really don't want to go down the street sounding like a bumblebee. I have listened to sound clips of both, but I would like some input on quality and if you are happy or would change some things about it.

Thanks

this may turn out very sick sounding. i've driven a new si and man their exhaust note stock sounds bad ass. if you get this done make sure to take a video!

Just for your information..sound clips offer absolutely no justice to an exhaust system.  An exhaust note has a large range, while the microphones used to record said clips generally have a very narrow recording range.  This is why Joe Schmo's greddy exhaust system on his civic sounds a lot worse than one you'd hear in "The fast and the furious".  A microphone makes all the difference in how anything will sound reproduced.  Another factor is the speakers that you are playing the sound through...Timmy could have a field day with all of this.  The best way to hear an exhaust is to actually stand behind a car with the exhaust you want.  This eliminates the nastiness you'll hear from a sound clip.  Instead of hearing the weed wacker sound that any exhaust will produce through a bad sound clip, you'll hear the deeper notes that the microphone cannot process and the speaker cannot reproduce.

For example..people ask me for sound clips of my exhaust all the time and I refuse to produce them because I know my exhaust sounds like crap when I've taken sound clips.  My exhaust in reality sounds freaking amazing as a few people (Namely anybody in my squad as well as Tim and Piero) will say.  I have no resonators so my exhaust note is very deep.  Most non-studio microphones cannot reproduce the sound that my exhaust makes, and all you hear is a metallic buzz because that's all the microphone can do to process it.

Thanks Skip, I talked to Mike yesterday about options with exhaust and he told me to hold off until I decide what I am going to do with my car.  I think I am probably going to go the same way he did with the turbo set up, since I live about 10min away from where Mike had his work done. Which brings me to another question for you, Mike and I got to talking about things I want to do this summer to my car and the TSX 6speed swap is my highest priority for things to do.  He told me to ask you to see if you could get the 6speed and intake manifold for me.

But in regards to exhaust could you describe what yours sounds like and what you are running.  I mean most people would tell me their exhaust sounds great or amazing, but that really doesn't describe what kind of sound it makes, and yes it would be best to sit behind one and hear it but it's kinda hard to find people in NC who have modified their Gen7 Accords.  But I will do some more research until the time comes to make the decision.

I gotta give my +1 to the APEXi. At idol it sounds just a little louder than stock with a low resonate tone that. It opens up as I approach 3500 where it gives a "woop" sound then anything above that is an agressive (not nasaly) ripping sound. No bee in a tin can here. Just to caveat, I'm running CD ceramic headers and maganflow cat before it.

ill throw in my hat towards apexi, ive had it for 2+ years now and am very satisified with it. The sound of it changes, subtly, with each mod. For instance, I have CAI, TSX IM, DC Ceramic Header. And i noticed a slight change in the exhaust note at different RPMs.

x1 on the apexi, i had my dual exhaust on my i4 for about three months and i love it..

+1 for Keith's A'PEXi.  It sounds awesome.

Anyone know how much trouble I will have getting the mid-pipe and axle back to fit? I know it will take some custom work...but trying to make sure this can be done before I start buying parts.

If I were in your shoes, what I would do is buy the mid pipe and muffler, have the shop just cut the pipe and only use the muffler, pre-muffler, and that resonator looking thing.  You may be better off having the shop remove your exhaust system and fabricate everything from the cat back.  That will be the easiest way to have this done.  I highly doubt you will be able to get those components to fit your car, so it's better to just use the components you want and have the rest fabricated.

Word. These parts can be had for cheap

I agree with Tim on this one.  The problem with the Si exhaust is that it is not made for use on an Accord.  The cars probably have entirely different mounting locations and it would be your best bet to buy the muffler of your choice and have an exhaust shop custom fabricate an exhaust system that employs it.  I personally believe that you will pay more for the entire Si exhaust with the pipes and goodies than what you would pay to have an exhaust shop use their on-hand parts.  This eliminates the butchering of a stock exhaust system, and allows the shop to craft a custom work of art for you.

Thanks for the insight skip.  I will take all of this into consideration.

listen to tim and skippy. They know what they are talking about. You could probably save some $$ also unless you can get the si muffler for cheap. Like for me I can getting 2 oem Tl muffler for 100. and going to put 60 for a 18in magnaflow resonator. and another 100-120 for labor and have them do the exhuast hole cut out. I know performance is not much but I really like how it looks. TL on accord looks so right.

For complete exhaust system i recommend APEXi WS system, Greddy evo, and for custom check out some here http://www.v6performance.net/forums/sho ... p?t=144756 (http://www.v6performance.net/forums/showthread.php?t=144756)

To be completely honest, I would highly recommend an A'PEXi WSII exhaust system for the i4 Accord.  It's a complete bolt on system so you don't have to pay for fabrication and could install it yourself with jack stands and basic hand tools.  It sounds awesome in person also.  It's quiet, mellow, but if you know how an Accord is supposed to sound, you know this is aftermarket.  I helped Keith install his A'PEXi WSII with a DC CC header and Magnaflow high flow cat, and it sounds awesome as hell.

I can also vouch for Apexi's temperate sound on the accord.  My buddy Nick used to have the WSII on his car and it sounded nice and quiet.  I was suggesting in the previous post that you get the Si muffler and have it integrated into a custom setup without the Si midpipe.  Just wanted to make sure my point got across the right way.  There are a number of ways to skin a cat and it's totally up to you.

Yeah, I understood what you were saying skip.  I don't know too much about exhaust systems...will not including the Si resonator (the round looking muffler before the muffler) dramatically change the final sound?

I do like the Apexi WS2...its just that it costs $500.  I can get a 2009 complete catback off 8thcivic for $150 shipped.

What is this thicker looking section on the stock Si mid-pipe?

(http://gregsphotos.glotzbecker.com/albums/upload/MISC/normal_0703_130_13z%2Bexhausts%2Bstock_vs_magnaflow.jpg)

It's probably a small resonator to reduce noise.  From the cat back, it looks like there is a resonator, a pre-muffler, and then a muffler.

Hrm...I wonder if the pre-muffler will fit under our cars...it looks longer than our stock pre-muffler.  Maybe I should just start with the axle-back and see how it sounds.

Our stock I4 pipe is 1.75" diameter right? I am pretty sure the Si is 2 or 2.25"

You'll be able to get it to fit somewhere under your car.  You will also be fine if you went up to 2.25" pipe.

Cool. I think this is going to be an EliteCM first in the making...

Well I guess the obvious choice is apexi lol thanks a lot guys that makes my decision making a lot easier.

We have a few of those going on right now.

Does anyone have this exhaust? Im looking into an exhaust system for my 05 Accord DX 5sp.

Any info on this set up would be awesome! Right now im debating between <a href="http://www.ilovebodykits.com/product/55759/Magnaflow_Cat-Back_Exhaust:Honda_Accord_2003-2005.html">The Magneflow</a> and <a href="http://www.ilovebodykits.com/product/48992/Greddy_Cat-Back_Exhaust-EVO_II_03-ON_ACCORD_V6_COUPE_DUAL.html">The EvoII</a> I am kinda leaving towards the magneflow because for the price of the greddy I can do headers and cat back.

Let me know what you think!

i used to be reallly interested in that kit, but then i saw it only came with 1 resonator, and that's too loud for my taste..

over on g7space, i believe Levi has it on his, with an added resonator, sounds sick, and looks stock.


the only reason i decided agaisnt this kit, is because with an hfp rear lip, those tips wont really do it justice.  IMO, i like the dual magnaflow 14829.

HTML doesn't work, please edit your thread with BBCode.

Magnaflow stopped making that exhaust a long time ago.  There's one for sale on eBay right now if you want to snatch it up.  It is a rare find.  I hated my Greddy Evo2 and replaced the mufflers with Magnaflow and couldn't be happier.

oops sorry Tim, didnt know html didnt work. Here are the fixed links  Magnaflow: http://www.ilovebodykits.com/product/55759/Magnaflow_Cat-Back_Exhaust:Honda_Accord_2003-2005.html    Greddy: http://www.ilovebodykits.com/product/48992/Greddy_Cat-Back_Exhaust-EVO_II_03-ON_ACCORD_V6_COUPE_DUAL.html

What I do not want is something thats wicked loud and obnoxious. I want some nice performance without the big fart can sound.

Is it going to alter the sound much/make it loud and shitty if I added DC ceramic headers and a magnaflow high flow cat to the setup?

Im going to have to hop over and check out ebay, thats for the heads up!

I'm extremely happy with my Magnaflows right now.  You can listen to them at the meet in June.

im def interested in hearing your setup. Are you also running headers and a high flow?

I was kinda hoping to have the exhaust done by the time we meet up in june. lol I know sound clips are not a good representation of the exhaust, but do you happen to have any?

I started out with a DC SS header, Magnaflow high flow cat, and a Greddy Evo2 for the V6 coupe modified to fit my i4 sedan.  It was ridiculously loud, so I had one of the Greddy Evo2 resonators cut out and replaced with a larger and quieter one to tone things down.  It was still too loud for my taste, so recently I had my mufflers replaced with the Magnaflows and I couldn't be happier.  I don't have any sound clips, but I could try when I have some free time.  Realistically, you're not that far from me if you want to try and meet up in person to listen to my set up.  Maybe on the weekend or something.

humm very interesting, i think im def gunna end up with the mags. Id love to meet up sometime and take a gander before just to make sure it is quiet enough for me.

I work in boston so if ur in that area, or would be up for a lil super mini meet lol let me know, im always up for a drive. Clinton is only 50 miles from me (Londonderry. NH)

Right now isn't exactly a good time.  The reason why is because I'm working on a new tune for my car right now, and it's running kind of rich at idle which makes it run rough and sound a lot louder.

ahh fun fun, hows the tune coming? Are you developing it yourself or working with a tuner on it

Im pretty much sold on the magnaflow exhaust. Dunno if im gunna do headers and a high flow cat yet though, ill add piece by piece and see how it sounds.

Im just waiting for my retros over on g7a to sell, then ill be reinvesting the $$ into an exhaust haha

GL on the sale man.  Since it's a bolt on system, the install should be cake.

Thanx, ima need it lol!

The only part of the install that might give me probs is the exhaust hangers for the drivers side, I have an I4 so its only single exhaust instead of dual, so I will have to find the parts and have them on hand for the install

Contact Magnaflow and see what they gave with the exhaust and try to get replacement parts.

My b, the exahust hangers I was talking about were the stock rubber grommets that the exhaust hangers connect to under the car.

I looked on majestic honda and found the parts I think I need

http://www.hondaautomotiveparts.com/auto/jsp/mws/prddisplay.jsp?inputstate=5&catcgry1=ACCORD&catcgry2=2005&catcgry3=4DR+EX+V6&catcgry4=KA5AT&catcgry5=EXHAUST+PIPE+(V6)

(2) 26564     011     RUBBER, EX. MOUNTING
(2) 34722    012    RUBBER, EX. MOUNTING

Ill be buying the exahsut new sooo hopefully itll be coming with everything in tact. lol

How are you buying it new?  As far as I know, they stopped producing this in like 2005.  Where did you find this?

I dunno, I thought they still made it. Ive found it on a bunch of different sites.

http://www.ilovebodykits.com/product/55759/Magnaflow_Cat-Back_Exhaust:Honda_Accord_2003-2005.html

all for the same price and no where did I see "used" or discontinued.

I sure hope it is still available haha

You have a V6?  I was under the impression you had an i4.  Anyway, Magnaflow has 16 in stock.

I do have an I4. I didnt think it would make that much of a difference though..

If I am wrong please enlighten me haha

I would consider a custom set up.  That exhaust system is made for a V6, which has the hangars for the DS muffler, but your car does not.  The flanges from the cat back for the V6 and i4 are also different, so that would need to be cut off and the proper flange would need to be welded on.  In my personal experience, exhaust systems designed for the V6 are louder when installed on an i4.  That's why I was so unhappy with my Greddy Evo2, because it was for the V6 and was significantly louder on my i4.  Considering the amount of money you'd be spending on an exhaust that would need to be modified to fit your car anyway, I'd get the mufflers and resonator yourself, and bring them to a shop to do custom piping for you.  I would strongly recommend coming to ESP for the work.  They did my most recent exhaust work, and when compared to other exhaust work I've had done, the final product is the best work I've had done on my car.  Be prepared to pay for quality work though.

hummm I didnt know about the issue with the flanges, I just assumed they would be the same. Would I be able to avoid that problem if I went with the high flow cat and headers, or would they still be different?

as far as the hangers were concerned I figured I would just have to buy the hangers from the v6 and install them when I did the exhaust.

If you dont mind me asking, how much did you pay to have your exhaust done?

The flanges are different.  When you buy a header and high flow cat, it's still flanged for the i4.  The only solution you have is to chop off the V6 flange and have it replaced with an i4 flange at the cat.  The OEM hangars are welded on to the frame of the car.  They are not a "bolt on" application.  You've been PMed with the exhaust price.

damn..... looks like im gunna have to have a shop do my exhaust... I was kinda hoping to do this myself

I was under the impression that the hangers were just rubber grommets that were bolted to the frame that the hangers from the exhaust "plugged" into.

The only way you're going to bolt on your own exhaust is to get a coupe.  For us sedan guys, we have no bolt on exhaust options.  You can only go with custom stuff.

I prefer custom anyway. Just makes me feel special. LOL!!! I got my custom dual set up done for a total of $600 or so, about $200 in parts and $400 for the install.

Derrick, you'll always be "special".  The custom set ups can be nicer because you have control of the parts used.

Exactly the reason why I like custom.  Thanks Tim! LOL!!!!!

(http://i95.photobucket.com/albums/l143/Sean_Alert/Crank-Yankers-03.jpg)

I see what you guys are saying and you make good points. Look like Im going to feel special tooo!!!  

Now that we have THAT figured out, I'm gunna need some help specing this thing out. Mufflers, resonators, pipe size etc... lol

I know Tim you like the mags you have. What size piping are you using?

I'm partial to the Maggies too. I've got a dual set up with the 14829's and a 18" magnapack resonator with 2.5" piping.  I would recommend 2.25" piping though.

Take Derricks advice.  Get 2.25" piping and get the 18" Magnapack with whatever Magnaflow mufflers you like.  Talk to ESP about it if you have time to come down.  They were really cool to me when I went there.  Just talk to Dave or Greg when you go there.

aight so 2.25" piping and magnapack. Ive looked around a bit and it seems like the favored mufflers on here are the 14829's. These shouldnt be too loud if I went dual's on my i4 right?

Not at all. I dont even consider mine loud with 2.5" piping except a little during initial start up.

hi, dont mean to jack ur thread but im doing the same thing but single not dual, and didnt want to re-post the same question u had, i notice u mention magnapack wat part would that be?, and also general question for everyone, if u replace ur resonator with one of the hi-flow ones would that affect emission testing?, and which resonator everyone recommends? thankz....

resonator=magnapack

I wouldn't consider it thread jacking, though we do frown on that sort of stuff.  Icebox is right, the Magnapack is basically a resonator, but more technically people call the Magnaflow Round Mufflers (http://www.magnaflow.com/02product/universalmuffler.asp?shape=round) resonators.

If any of you are interested I have exchanged messages witht the guy that was selling the sedan catback on ebay I can get it for 400 shipped anyone want it?

I am interested depending on whats it comprised of?

link?

Its posted in the Ebay/ Craiglist deals section I have made a deal witht he seller out side of ebay for 400 shipped. I'm just trying to hood up a sedan owner. It is the exhaust that magnaflow made for the sedan I think they are a pretty rare find. Check it out

checked out the exhaust, this is the same one posted above, I think for 200 less then the price up there I could afford to have someone cut off and weld on the flange for the i4 lol. You still in contact with this dude, I tried to email him but couldnt figure out how on an ended auction? Do you know is the exhaust is still available? If so mind passing along my info email: limongelli.steven@gmail.com

Thanks

I'll pass it on next time I hear from him. I sent him a few questions through ebay.

thanx bro!!

dont waste ur money on the SI exhuast. My friend got one and it doesn't fit. wasted of 60 bucks.

I'm a noob when it comes to mufflers. So far i've went to auto shops and got quotes. First off I would like to know if a universal magnaflow muffler for $190 with installation is a good deal. Second if I decide to go with it how will it sound? I'm looking for something not crazy loud, but like a nice roar to it. Any recommendations??

thats is a good deal. the muffler itself can range from 60-110 bucks depends on the magnaflow.

well he's trying to use the muffler from the SI, not the whole exhaust system...i think.

**UPDATE** so this past weekend I drove down to Brooklyn to meet up with J (G7A) member to buy his old single exit ehxaust.

Specs
2.25" OD piping
18" MagnaPack Resonator
Magnaflow 14829 Muffler

Spent Sunday afternoon lying on the nice cool cement floor of my garage putting this bad boy in, and I couldn't be happier. Took about 5 hours (thanks to my buddy Tayler and Tiff) to unbolt the old exhaust and bolt up the new one due to some HARDCORE rusted and seized bolts, but all in all everything went very smoothly.

Sounds is great, and I feel like the car pulls a little harder (could just be wishful thinking lol) I took the parental units for a ride in it last night and even they liked it (I was pretty surprised at that haha)

I had my friend Tiff take some pics that I will post up once she gets them to me.

Thanks everyone for all the advice, you all DEF know what your talking about!

Right.  Still have not decided on this or not.

yeah it was too long. He had to have it hang to the ground, but he was like screw it since he wanted to fit it on his cut out

Does it bolt right up to k24 accords?

It will bolt right up no problem.  It's not the right size though so you'll need to extend it and you'll need to make your own exhaust hangers, but header back, the 3 bolts used to bolt it to the header are indeed the same.

The TSX exhaust manifold is a different length from the Accord exhaust manifold.  That's why all the TSX owners were having issues when DC came out with their headers.  They just used a header for the Accord, and the TSX owners were cracking their header.  It was later discovered that they were not the same length and DC made the adjustments.  I'm sure if you took the TSX exhaust to a decent shop, they will be able to fabricate hangars so it will fit properly without any issues though.

would you guys recommend the I4 staying with a single exhaust versus the dual ?
obviously its a little cheaper for me... personally i dont see a huge performance increase from doing the dually

im looking to as much performance as i can.... with just a little sound, this is my daily driver and i DO NOT WANT A RICER SOUND
i have an AT with a bunch of bolt ons....

thinking of doing same set up....

2.25" piping
18" magnaflow 4" round resonator - $65
14829 magnaflow muffler - $145

would bumping the magnapack to a 6" round be a little overkill?

does anyone know the diameter of the exhaust port on the bottom of the DC ceramic 4-2-1 headers? or the OEM CAT converter?
trying to figure out how much hardware/flanges/clamps i will need

I think you will like this setup. I had basically the same requirements, performance and non rice sound as this is my DD also, and this more then satisfied both!

I would say stick to the single, I think the dual would be too loud.

I was skeptical at first but DEF noticed a bit more power in the car. It def pulls harder in the lower RPM range.

Also, the sound is VERY nice. It is a little loud at start up, but once the system warms up it quiets right down. It has a very nice deep tone, and sounds like pure sex at WOT.

The kid I bought the exhaust off of described it as being very similar to the G35 sound and I would have to agree.

awesome man... im pumped...

waiting on this kid to get me shipping info and diameter of downpipe connection on it for the DC ceramic headers..... then i have everything else lined up
i guess i'll start pricing muffler shops to do the work

sucks i have an AT
makes exhaust not as much fun

sweet man!! you will have to let me know how you like the DC ceramics I am thinking about adding those along with a magnaflow high flow cat to this system.

At or MT I am pretty sure your going to love this exhaust!

Keep us posted

Is the TSX exhaust any better than the stock Accord's? Seems to me like most factory exhaust systems are always not good, lol. But, if the price is right, I'd definitely say that it could be worth it.

I think the piping is the same diamater so I wouldnt necessarily say it's better than the Accord but it could be in a sense because the TSX engine is better than the Accord therefore it needs to be better in order to expel gases properly.

I expeled some gas, it was properly though

Isnt the TSX exhaust dual? Wouldnt that be a minor benefit?

i could be wrong about this but, that box just before the muffler is that a resonator?

yep. from what I remember on old G7A...some people removed it and thought it sounded raspy.

so basically it isn't worth it? :P

thats what i thought. i dont think it would be to loud like the pop cans some ricers have...

Considering that the TSX's K24A2 has a higher flowing head with performance VTEC and the intake manifold is a common upgrade for us, it would only be natural that the exhaust would also be an upgrade to our exhaust.  A + B = C.

Is it easy to take off? Or should I just walk away right now to prevent any further abductions of the evil rice powers? XD

Sure, you can call it that.  It's basically just a pre-muffler.  Resonator = Muffler

Doesn't Rolo have it?

Not that I know of.  You may want to ask him directly.

Nevermind, i looked at his profile. It is coupe v6 exhaust.

I have the Gen7 coupe V6 dual exhaust.. (Thanks to JT Blackhawk)  

removing the resonator with stock exhaust is a waist of money i say wait until you get some mufflers and get a performance resonator cuz the engine drone will kill you

^agreed. engine drone suuuuuucks on long drives

just do the full piping and new muffer + resonator. Do it right or don't do it at all

alright just asking. i am not doing a full exhaust until my stock one goes. i was thinking about just ripping out the resonator and welding a pipe back in. it wouldnt cost me much. but i dont want it to be that loud. i jsut want a little sound. i know that it wouldn t do nothing in terms of performance.

if you do a straight pipe your gas mileage will go down the drain

Please explain.

How would gas mileage go down? All the resonator does is "muffle" the noise coming out of your engine. The only way gas mileage will go down is if you're constantly on the "go" pedal just to hear your raspy exhaust.

Ah yes, the exhaust system. Everything is so tempting at this point, lol. Lemonjelly, how much was the price out the door?

I ended up with a sweet deal, I found a kid on G7A who was parting out his accord who had this exact exhaust already done and was getting rid of it for REALLY cheap so I scooped it up. If you really want to know what I paid for it I can pm you the price.

He is currently selling his evo2 (single exhaust) that he had extended for his sedan. He is looking for $550 + a stock 06-07 exhaust in its place. He has only had the evo2 on for a few months and it sounds really hott. He fired it up for me when I was down in NY picking up his old exhaust.

Here is the link to his post.

i dont know how that could possibly decrease fuel economy. might increase fuel economy by 0.00002%

Eh, I'm not sure I'm willing to drive all the way up to NY just to pick it up, lol.

Thanks anyways. I'm sure my time will come when I find an awesome deal just like you, lol.

EEEK I wish someone had chimed in sooner, but DONT WASTE YOUR MONEY ON A MAGNAFLOW.

You mine as well order a REAL muffler online and have someone else install it.  Order one that is designed for your car!!

I know this has already been talked about (at least on the old Gen7), but what's the stock diameter piping?  I'm thinking about going back to that size that's why I ask.  I remember it being a little over 1.75"?

Does anyone think I would get some of my backpressure back simply going from 2.25" to 2"?

Yeah, you're correct about the OEM size.  You may gain a little more backpressure if you went down to 2".

i disagree. i have a magnaflow 14829 and i am pleased. i also swapped out to 2.5 inch piping

^+1 on getting a custom exhaust, I wish I had gone with one myself

I would also agree with Timmy.  I really don't see too much of a harmful drop in backpressure with having a 2.25" exhaust, and I do not think that it's worth it to go down a quarter inch and shell out the money for a new set of pipes.

Rolo- Did the v6 coupe exhaust bolt right up to the existing exhaust manifold?  Did you notice any performance gains/losses?  What about the hanger placement i.e. bolt up to the stock locations?

To all-  Has anyone actually done this?  Pics of the install would be great!  I was also considering this setup, as long as the price was right, of course.

To the first one, no because he has the K24. It had to be modded. As far as the hangers, its possible one of them lined up after modding, but a new one had to be installed on the driver's side.

As for the second one, I was in the process of getting a hold of a Comptech exhaust for the TSX from a guy at work that hates the sound (he bought the car with it on). I ended up ditching the idea after his reluctance and wanting to get money out of me when I already offered to buy a stock exhaust to swap with him.

so im thinking about getting a new exhaust with a bigger inlet. im running a 2" inlet with stock piping (YES I KNOW ITS A FAIL). im looking at some mufflers and finding some that i like, but the inlet is 2.5" im thinking about getting the piping redone from the cat, which would make the diameter of the pipe 2.25", and the exhaust inlet 2.5"

would there be any loss in TQ or HP if theres a size difference like that? or should i just stick with finding a 2.25" inlet. thankss

You should be okay at 2.5" but, I wouldn't go bigger that.

so i dont like the sound coming from my NRG muffler. im wondering what exhaust i can get to just get a quiet but deep tone at idle and lower rpms, and a somewhat deep roar and higher rpms. i dont think im gonna go with magnaflow, just cuz of the feedback ive heard from people in the past, and i dont want to spend like 300 on a muffler either.

im thinking about going duals (i have a i4). i was thinking about megan racing. if anyone has had good exp with them, please share. if you would, just give feedback on what exhaust you have and how much it was. thankss

You get what you pay for at the end of the day. I would go with Greddy, Magnaflow, Borla, and stay away from the megan racings of the world.

i know your new here and many people have made the mistake of making new threads on topics that have already been discussed...but you really need to search the thread more.

i have magnaflow mufflers on my car and it sounds real good.

here is a site to order muffler parts from....  http://www.performancepeddler.com (http://www.performancepeddler.com) my mufflers retail for like $150 and i got them for 100 each on that site. they allow you to give your best offer

I've had my Borla's on my ride for almost a year already and I love the way they sound.

Borla's are only made for the coupes, but mine were a 98% direct fit onto my 06-07 sedan.

+1 on the borlas.  ive had mine since about a week after i got my car (5 years ago) and love em

i have a magnaflow 14829 which many people here have. i like it , it was cheap ( around $100), then i had the muffler shop install 2.25 inch piping and a resonator.

okay, another quick question, so what if i upgrade to 2.25" piping, with a muffler with a 2" inlet. i know that would create some backpressure, but thats better than stock piping with a 2" inlet right?

You'd be better off keeping the 2.5" inlet muffler with 2.25" piping. Why create a bottleneck at theend of the exhaust? It'd be the same as your current setup. Also, if you don't run any resonators in your new setup, you're going to sound like every other ricebag on the road with a loud raspy fartcan exhaust.

k cool. the reason i asked about the 2" inlet was because the gay muffler i have right now has a 2" inlet. but yeah, thanks for the help guys. ill probably go with the first setup listed above

that is a yes and no depending on what muffler he went with, cause i have 2.5 piping with apexi ws2 (2.5 also) no resonators and it was quiet as can be,not raspy, but then it comes back to what you buy. quality or crap

True. It does depend on what you buy but I believe the WS2 is chambered. OP, what muffler are you planning on running?

yeah that is correct , it is chambered which is why its so quiet, i know someone local (miami) is selling a ws2 , or he could go greddy evo but there a little loud for my taste, i like the quietness of the ws2 since specially when cruising its like stock.

can a admin close my 2 previous topics? dont wanna open up a 3rd one about a different subject and look like im spamming

After looking at the topics you want to close there really is no reason to close them dude. They're not in any way spamming. You're just curious, plain and simple. No sense in closing up topics unless they're reposts.

With regards to exhaust brands, everyone has their own opinion. Search around YouTube or something like that for exahust clips to get an idea of what you're after. Maybe go to an exhaust shop near you and see if they're willing to work with you on different mufflers to try out the sounds or whatever. I'll tell you one thing though, on my DA I went through 4 different exhaust setups until I found what I was looking for. You may end up doing the same.

if you want something quiet the apexi ws2 is great, can pick up a used one for around 120-150

Not meaning to revive this thread from the dead, but I know a friend at my school that has a ~07-08 altima 2.5s who removed the resonator on his puny dual exhaust. Needless to say, it sounds like total shit, like a ricer rasp. But, I don't bad-mouth him since it's his car and he can do whatever he wants. I'd imagine that it'd sound pretty similar on our cars.

i took mine off with stock piping and a muffler. HUGE FAIL.
sometimes im embarrassed to press on the throttle. doesnt sound super bad, just really bad.

needless to say, dont do it unless your getting quarter piping redone to 2.25. my friends eclipse with 2.25 from the cat and no res sounds pretty good

did you have full exhaust stock? headers and all.

Yeah he has the stock exhaust 100%. All he did was remove the resonator. I don't plan on doing anything exhaust-wise to my car unless I end up getting the full exhaust redone, headers and back. It's a lot of money to pump into my car for an exhaust.

did you hear it persoanlly. did it sound ricey???

It sounds really ricey. It's pretty bad when he turns the car on cold, but it does get a tad bit better after the car has warmed up. I wouldn't have done it if I was him.

so the stock exhaust piping is a 2" opening? not 1.75"?

looking to get a high flow cat and im trying to match up the piping to my DC Sports 4-2-1 headers flex pipe which are 2"

or should i not deal with getting a universal high flow CAT (which requires some cutting and welding) and just go with an OE replacement like this?
http://www.autopartswarehouse.com/detai ... ab9e&gan=1 (http://www.autopartswarehouse.com/details/QQHondaQQAccordQQEasternQQCatalytic_ConverterQQ20032004QQEAST40400.html?apwcid=P1135867996W43b3f85c7ab9e&gan=1" onclick="window.open(this.href);return false;)

I'd get a bolt on aftermarket replacement.

Haha, sorry to revive an old post.  I haven't been on for a while, but this post has gotten me excited so I must share!

The TSX exhaust is actually a very good (and straight through) design.  People who do upgrade their TSX exhausts to an aftermarket do not find too much of a hp gain from what I gathered.  It's really all for sound!

Here's a post for more info on the TSX stock exhaust:  http://tsxclub.com/forums/1st-gen-engine/28924-acura-tsx-stock-exhaust-8.html

hey guys, so I'm thinking about doing something with my exhaust. I'm thinking maybe the magnaflow kit MAGNA-15799?
http://www.essentialgears.com/tho/tr/pr ... 28374.html (http://www.essentialgears.com/tho/tr/product/03-HONDA-ACCORD-MAGNAFLOW-CAT-BACK-SYSTEM-3928374.html" onclick="window.open(this.href);return false;)

 From the pictures, or from what I've been able to see, it looks like a 4" opening, and 2.5" from the cat back? Would that just look too ricer if I had a 4" exhaust opening? Would a kit for the v6 with dual tips fit a K24?

Woah!  They actually sell that still.  I was under the impression that exhaust was discontinued like 6 years ago.  I have 4" exhaust tips and I think it looks badass.  The V6 exhaust will "fit", but you'll have to have a shop cut off the V6 flange and weld on the i4 flange so it will bolt on to the cat.

cool, does anyone know what this sounds like? I want that nice deep sound, but not that urber loud high pitch annoying sound...

im sure there's a million clips on youtube.

personally, i like the look of a more OEM exhaust that still sounds good

I have the Greddy evoII with a megan racing cat-delete....and I love the sound....it doesnt sound rice at all.

Of course, I have cai, intake manifold, and ceramic header, so im sure it helps the sound.

Hey guys, guess im looking for or trying to get some ideas on what 4 door owners have done for an exhaust. I have a i4 , 4 door and I cannot find anything so im hoping to get some good ideas, links, or responses of what you guys have done who have a i4 4 door set up. the help is greatly thanked!!!!

http://elitecm.net/forums/index.php?topic=990.0 (http://elitecm.net/forums/index.php?topic=990.0)

I like the looks of the magnaflow just wish it wasn't for dual, which wouldnt be a problem to hook up but would that require addition hangers and everything? im trying to keep a single outlet but thatnks for the link alot of help!

So I would be better off buying a muffler, resonator and then going to the shop and having them basically custom fit everything is what im getting from that thread because there are no bolt on i 4 kits ha
2.25" piping
18" magnaflow 4" round resonator - $65
14829 magnaflow muffler - $145
good or bad??

First thing's first. What year is your car? If its an 03-05 model, to make that muffler look right without being angle down or hanging lower than the stock one, you'd need to make an exhaust cutout in your bumper. If its an 06-07 model, you already have the cutout so it'll be smooth sailing. Secondly, the list of parts you mentioned is a good way to go especially for a stock car. Personally, I did go the dual route and had the hangers and shit done to mine as did Tim (timot_one) and Jeff.

A little off topic, why don't you create a profile thread so the rest of us know a little more about you and your car? Its a car forum so, obviously we like to know more about the cars and people who are members here.

You can buy a coupe exhaust and have a shop extend it a little to fit your sedan.

That's what I did. Thing is Mike, I don't think he mentioned if he wanted to go dual as he only priced out a single muffler.

Just buy a TSX exhaust.

You can get a single exhaust for a coupe I4

I have seen those too.  My vote is TSX exhaust.  Less bullshit to deal with.  No modification required.

True. Unfortunately, when I did mine, the dude I was going to get the CT exhaust from flaked.

I have 05 acoord 5 sod manual and i was looking to keep the single 4 cyl

Here's some info on the TSX exhaust:

http://elitecm.net/forums/index.php?topic=1134.0 (http://elitecm.net/forums/index.php?topic=1134.0)

I must be psychic or some shit. The man wants single. Do you want the straight out exhaust or do you want it to turn down like stock? All depends on what you want done exactly.

Yes I was trying too keep a single pipe out with a setup that will give the best sound . Deep toned. I am willing to shave my bumper to make it fit but just trying too find and price everything . Just don't really want the big tube hanging out the back lol but I'll take all ideas. Just looking for one that will overall. Be a bolt on or one with minimal modification thanks guys for the help!

Or what year tax should I look up on exhaust company sites to get the right exhaust? Just trying to get what my options are figured put so I can buy one !!

Will it sound good or what should I expect the sound to be like on  my i4 four door accord + CAI. Will it be ricey or will it have a better sound than most of the fart toobs out there for i4's. I was trying to keep away from getting a tube , but if anyone has something that does give a deeper sound please share!! I really am looking to keep a good tone, but nothing that drones, and that will have a deep tone for a i4. BTW my car is also 5 spd if that will make a differenece to the sound. here is a video that i ahve been referencing..  07 Honda Accord 4cyl 4dr w/ Magnaflow Exhaust #14829 (http://www.youtube.com/watch?v=FqL2VmGdbHM#) witht he camera being right behind the muffler it adds some bad air sound but i think it would sound good but I know you guys have experience with it so just wondering.

Alot of members have used this exhaust please search before posting new threads.

Please don't create multiple threads for the same topic.  I have merged the two exhaust threads you have created together.  

Whatever  exhaust you decide to get, each will have their disadvantages and advantages.  As far as the sound goes, you'll find out what it sounds like if you listen to another Accord like yours with the set up you want.  Some set ups sound good and some sound raspy.  From what you've posted so far, here's what it seems like your best options are going to be:

1. Get a muffler and resonator and have a shop weld it for you with new pipe
2. Buy a coupe cat back system and have a shop modify it for you
3. Buy a TSX cat back system and bolt it on

Commit to one of those choices and accept the consequences of your decision.

So I have the  DC Header with an extended flex pipe and custom dual magnaflow exhaust w/ 18" resonator on my '05 i4 coupe. Recently I started noticing a "ticking" sound when the car is running. The ticking persists after the car is shut off (which seems common on many cars, the result of the pipes cooling down)... but I can literally hear this when I pull up against anything solid (a drive thru for example. If I had to compare the sound to something, it would be like tapping a knife or something against a metal pipe. It occurs every 5 - 10 seconds, and gradually slows when the car is turned off. In addition to this, I'll feel a somewhat strong vibration coming from the rear of the vehicle when stopped at lights, which will go away if the car is put in neutral. Any suggestions as to what might cause this? Please let me know if there's anything else you need to know. Thanks.

Where is the ticking noise coming from?

It seems to alternate between the resonator, the cat... it's hard to pin point the exact location... it's intermittent too... I suppose it could be leaking at one of the welds if it's even a leak... I wonder if there's a connection to the vibration as well.

So i am about to purchase the Tannabe Touring medallion exhaust system from the local area.  The problem is the tannabe exhaust is made for a COUPE V6 while i have a I4 sedan! I did a lot of researching but could not find much. 
I know i need to modify the bumper with cutouts and add a extra hanger. 
The piping diameter is 2.5" and im not sure what the piping for stock sedan is but would i need an adapter piece from flex pipe to exhaust?
How about the length of the pipe? 
Am i better off buying a oem tsx exhaust from the junk yard and modifying that or get the V6 coupe tannabe touring exhaust?

Please let me know, need some advice / help.  ;D

Seeing as how I have the OEM v6 coupe exhaust on my car, like you said, you need hangers on the DS and you would need to extend the B pipe on the exhaust itself where it would normally bolt to the cat. That's basically it. Don't worry too much about doing anything to your stock cat or exhaust manifold. An aftermarket header and cat will solve that size issue. Other than all that, just buy the exhaust and enjoy.

Thanks for the fast reply man.  cant wait to make the purchase now  :)

That's what I'm here for.

So i need some advice about installing and pricing. The part is a V6 tanabe cat-back dual exhaust.  I am trying to get it installed on my i4.  I went to a local exhaust shop whom quoted me 300-350 for the install.  They mentioned that the end flange of the Cat will not connect properly with the tanabe flange; ( The accord V6 cat flange is bigger and angles compared to the i4).... His plan was to cut the end piece of the tanabe that fits into the Cat and the end flange of the cat.  He would than weld the two together.  Install some new gaskets and put up the hangers where its needed.
Has anyone tried to put a 2.5" pipping dual exhaust on a 4cy accord?  if so how did you or the mechanics install it? and whats the price range for the install? 

Thanks

Well, $300-350 seems a tad high, considering that the Tanabe exhaust should be bolt on for the v6 Accord, right?

When I got mine installed, the guy took out the premuffler, and used that space to add the extension. He then welded new hangers for the two mufflers in the back, welded a third flange onto the Y pipe where the i4 hanger is, cut off the third cat and welded that to the pipe right after the flange that hooks up to the i4's cat. It only cost me $100 plus the leftovers from the old exhaust.

My old exhaust was a Greddy Evo2 for the V6 coupe.  I did it a bit differently though.  I replaced everything from the head back.  I had a new header, replaced the cat with a high flow cat, and then had them modify the exhaust to fit.  They just welded everything up to the new cat.  It was kind of a hack job though.  I prefer my current exhaust set up now.  Much better.   :thumbsup:

Has anyone tried the Megan Racing High Flow Cat?

I've read this entire thread and am still unsure on what is required to properly install an OEM TSX exhaust.  ???

I have a 2005 i4 sedan.  From reading other forums and threads, slight modification to the TSX may be required.  Would anyone know the following:

1) Is the OEM TSX exhaust a direct bolt on, particularly the CAT flange, hanger brackets (dual outlet), location of dual exhaust tips at the rear bumper, overall length of the exhaust, etc.?
2) If not direct bolt on, what type of adjustments/modifications need to be done (e.g. extend or shorten the CAT-back exhaust system, add new hangar brackets, weld new flanges, cut out new opening at bumper for dual outlet, etc.)?

Thanks!

mainly new hangers, but unless your getting someones old exhaust for free, i would recommend going to a muffler shop and getting a custom made cat back for $200.

^^ Wouldn't a custom exhaust be more than $200 total?  From what is gathered throughout this thread, the custom Magnaflow setup (single or even dual outlet) will be roughly $200 just for parts.  Labor would add another $100-$300??

I have a magnaflow 14829 mufler that i bought on amazon for 100 then had the shop do the rest for 150. it was a great deal and performs better than the stock tsx exhaust.  imo dual exhaust on a 4cyl is for looks and has no performance gain.

^^ Thanks IceBox.  What other exhaust mods were included (header, highflow cat, increase piping size to 2.25" diam., etc.)?

As far as the OEM TSX exhaust goes, if I do get it for free, than I'll go that route.  To increaes flow and sound, maybe remove the "pre-muffler" downstream of the CAT & resonator.  Agreed that it's just for aesthetics.  Might do that and a header designed for the TSX as well  ;)

im still running a stock cat, i did 2.25 piping and a resonator to keep the sound down. im also using a dc sport ceramic header. i dont believe there is any difference between the tsx and accord dc sports header.

Actually, there is a difference between the headers.  When DC first started selling the header, there was only one part number, which is the current Accord part number.  It turns out that the TSX guys were getting them and they were cracking because there was a slight difference in the length of where the exhaust flange was.  I think it's a slight difference, but it was enough to cause damage.

I'm lookin to redo my exhaust and upgrade to a DC sport header, but I want some opinions on whether or not I should remove the cat and go to a test pipe, what diameter pipe works best with the header, and if anyone is using a y pipe to get the dual exhaust look

quick question.. what needs to be done to modify a coupe exhaust to fit on a 4 door?years 03-05

Funny you mention that as I happen to have an 04 coupe exhaust on my 05 sedan. Extend the pipe on the exhaust and add hangers to the driver's side. Definitely take it to an exhaust shop to get it done as the OEM I4 exhaust has a funky ass hanger on the muffler whereas the AV6 coupe exhaust has more "traditional" style hangers. Also, make exhaust cutouts and don't be a bitch like Jeff and let it hang under the bumper until convinced to cut.

how much does the pipe need to be extended

Hey hey, at least I did it!

I would probably say that the exhaust has to be extended about 6 inches to a foot. It's hard to say when the exhaust is on the car, and the fact that I dont even have that car anymore, lol.

Ha! I knew that would get you!
Anyway, Jeff is right. It needs to get extended about a foot.  A decent exhaust shop will be able to figure it out.

Also, if you want to, you could remove the pre-muffler. That'll make it sound a little louder. It'll give the exhaust shop a place to put the extension pipe.

Also true and something I did.

Nice to know that a coupe exhaust setup has to be extended about a foot. I will be sure to let the exhaust shop know of this so they have a heads up on what I want done. I will be purchasing my dual setup real soon.

Just purchased an N1 Jdm Catback Exhaust, installing it tomorrow.

I know someone who has a real clean Borla setup for a V6 coupe that he's probably willing to part with because he's to lazy to install it.

That lazy fucker is always lazy about installing shit.

 :PM:

^ I honestly don't like it. To me, doesn't look right on an Accord but we all have different tastes. ::)

Its definitely different but not for me or most everyone. Either way, its your car. Not mine.

i am thinking of getting tanabe medallion touring exhaust. anyone know how it compares to apexi ws2? also will the tsx dual exhaust fit the coupe 4cyl. i think i remember reading somewhere that i have to modify the hangers???

I've only heard a Tanabe Hyper Medallion on a 3" exhaust set up on a boosted K24 and it was ridiculously loud.  There was no cat, no resonator or anything though.  Just straight pipe back to a split and 2 Tanabe Hyper Medallions.  The TSX exhaust will fit with minor modification.

Would going with the tsx setup hurt my performance? (because of the dual mufflers) The accord one is 60mm piping all around the tsx is 60mm/50mm

Do you know what I'm running Fab? Also, where the hell have you been hiding?

Hahaha I've been out of the game for a bit. Your car is looking dope! I'll be sure to check out your profile

Ur running the v6 exhaust. Any power gains?

Would anyone be able to confirm that the location of the each ('04-'08?) TSX mufflers/tips will align with the '03-'05 rear HFP coupe lip?

The stock exhaust doesn't align...

I think it does. The differences between the TSX exhaust and the Accord exhaust are a few inches but other wise the same.

Fab, I felt a bit of loss in the low end but I think I can attribute that to the TSX IM as well. It does flow better than our tiny stock exhaust and would actually be a 99% direct bolt on for you since you have a coupe. IIRC, you may have to swap the flange that bolts to your cat and add a hanger or two.

Thanks Mike and Z.  Definitely read that the length of the exhausts differ between the Accord and TSX.  Just hoping that that the location and distance between the mufflers/tips closely aligns.  Save some costs and time with any drastic modification.

Agreed. I'm not too sure on the muffler spacing but I'm almost positive they are the same as the v6 Accord's spacing.

I also had the Accord V6 exhaust on my old car, and I too noticed a loss of low end torque, however it picked up a heck of a lot of power in the high end. Honestly, I probably wouldn't do it again, unless I knew for a fact that it would not hurt the low end performance. Z may think differently, but since I have an auto, my car pretty much always sits below 3k RPM. Since his is a manual, he can probably feel it a lot better since he has more control with the RPM's.

Truth.

I can't risk losing anymore low end. That plus 4 people car drives like shit! I just got quoted $1000 for the accord Tanabe medallion touring and 1500 for the tsx medallion. Might just get the accord cat back. I'm not paying 50% more for an extra muffler and some piping and still have to modify it

I'm just hoping that a catback will bring some low end torque back

It won't. Taking it to stock would. As for the added weight of people, I just recently drove from Miami to CT with my kids in the back and a trunk loaded down with luggage. It wasn't as bad as you describe. Surprisingly, I got gas mileage in the mid 30's the whole way and I was doing 70-80.

Anyway, if you want your low end back, you have a few options. One, put your stock IM back on and throw the appropriate exhaust onto your car. Two, leave the TSX IM and your exhaust alone. Three, change your exhaust to something larger, slap on an M90 and tune it.

What would u rate the Catback top, mid and lower end gains out of ten

Couldn't say. My setup is "stock".

Wait, since when did the TSX IM hurt performance? It helped on my old car.

It hurts a little on the low end. Its meant more for the upper RPM band as is the engine it originally came off of.

Tim what's your expert advice on the matter.

Fluid dynamics and exhaust tuning were never my strong suit.  In the same right, I don't have a stock motor any more.  Realistically, the only way to tell which is better in whatever RPM range is to get it on a dyno before and after the exhaust.

Man speaks the truth. The butt dyno can only tell you so much.

Would you say that the stock IM & 60mm Catback exhaust provides more lower end torque then a tsx IM & stock exhaust?

Bump

your better off with the tsx im.

Damn it! I want more performance

Das boost.

Unfortunately, you have to pony up and start spending real money when you want power beyond bolt ons. It's a big jump in price when you go from bolt ons to performance parts that will net larger gains in power.

Like I said. Das boost.

So as some of you may or may not know I recently installed the Magnaflow 16686 Dual Catback Exhaust System (http://www.magnaflow.com/02product/displayapplications.asp?partnumber=16686) ...is there any way to get the tone to decrease alittle? I mean when the car starts it sounds great, then you don't hear it at all but once my foot touches that gas petal I feel as if it might be alittle too much going on for my liking. Wondering if I can add something to the straight pipe...? I honestly wasn't expecting it to be so loud or maybe since I was just riding oem for so long as it is quiet I just gotta get used to the new sound!

Add a resonator.

Any particular one I should look at?

Somewhere in this thread, there's mention of a magnaflow resonator. I'd look for it but I'm posting from tapatalk right now.

You can add a "resonator" or muffler. If it were me, I'd get the largest diameter and longest Magnaflow muffler with the same inlet/outlet diameter as your exhaust that you can fit in that straight pipe section. For reference, I have a 6" diameter 30" long muffler on my 3" exhaust.

(http://i24.photobucket.com/albums/c14/crazycreashunz/16686_lg-1.jpg)
V6 3.0L; Coupe
5 x 14in. Muffler, 4 x 18in. Resonator; 2.0/2.25in. Tubing; 4.0in. Polished Stainless Tip; DUAL REAR EXIT

...So this already comes with a resonator where the arrow is pointing takes up 95% of the straight pipe, where would I stick another resonator...  can I weld it in right before the split off into the dual. Or should I take out that resonator and replace with a different one.

That's the V6 coupe set up.  Don't you have the K24 sedan exhaust?

Na Tim, Billy just recently bought a Magnaflow Dual Exhaust.

Yea I had the stock exhaust forever, I got this because of the deal, I just had them add some extra straight piping to extend it so it fits. I'm actually liking the sound now that I drove the car today for awhile. Even on the highway it was a nice tone. I guess I just had to get used to it lolz.

...I read somewhere scrolling through this thread that adding a V6 exhaust will be a bit more louder on the i4, so I'm dealing with it lolz

That is correct Billy.  Did you ever hear my car when I had the Greddy Evo2 on it?  It was out of control loud.  Even after I had the resonators replaced, it was still stupid loud.

There was an S2k at the meet last night with an Invidia catback... Talk about fucking loud!  Look em up on youtube... Shits cray. Lol

HKS Hi Power was the best exhaust I've ever heard on a S2000.  There was one guy that lived near me in MA that had an exhaust on his S2000 that made it sound like a fucking bike.  It was awful.

Speaking of loud exhaust, Cham's car has the loudest most brutal sounding exhaust systems on an Accord I've ever heard.

that exhaust is terrible.. my buddy had one when he had his S.. I hated riding in his car

My favorite sounding exhaust for the S is ASM..

I kinda like it... Lol.  Just dont think I could ever have one with it, especially not a daily.  But now a weekend warrior... Def! Cause thats wjat theyre supposed to be! Haha

I couldn't take an exhaust that loud even for a weekend car

How was the CT-E exhaust?  I know those are known for being loud.

actually, it wasn't that bad.. it did drone a bit, but not incessantly bad that turning up the volume didn't fix..  some folks did comment that it was loud when driving next to me on the freeway, so I think it was definitely one of those exhausts that sounded louder outside the car than inside..  unlike my friends Invidia, which was stupidly loud both inside and outside the car..

Definitely quieter than an Invidia or the Js Racing 70RR..

I never did get a test pipe, which apparently helps with inside drone..

What sort of options are there for dual outlet k24 sedan?

custom.

Like David said, custom is the only option.  Actually, there are no options for sedans. 

Truth. You could look at the v6 options though but you would still need to customize it a bit.

^

Custom blast!

I think a TSX or Coupe i4 option would be better than the V6 option as long as they're extended

TSX isn't a bad alternative.  Some of them are usually more expensive than custom though.

my personal recomendation in to pick up a couple maganflow mufflers of the internet and take them in to a local exhaust shop and have them weld them up with some bigger diameter ss piping.

That's a much better option actually. Just make sure the shop does quality work and uses good material. I've been through a few exhaust shops and a lot of them hack shit.

i chucked out the stock catback for a cusotm 2.5" exhaust and the primary A/F sensor conked out. coincidence?

Not really. How many miles are on the A/F sensor?

33,000km or about 20,000miles.

That's pretty low for a sensor to crap out.  Did you check the wiring for damage?

the plastic coating seems to have rubbed out exposing some wires.

i got a P0134 code (AF sensor heater malfunction). replaced the sensor with a new Bosch and now it's all good.  :)

Yeah, damaged wires makes sense then.  Make sure the wire harness is secured so that doesn't happen again.  I believe there is an issue with using Bosch sensors on Hondas.  That may cause you problems down the road.  If you can, try to use Denso sensors.

That depends Tim. On which Honduhs are we talking about?

My Bosch has been running like a champ for about 3 years and roughly 40k miles. It was conveniently sold at a local parts store.

I've read that Bosch sensors are not good on newer Hondas.  I have never used a Bosch sensor because of that, so I have no experience.  I've always used the OEM Denso sensors.

I've read it too so I'm not refuting it at all. I was in a pinch when mine went. I was also just sharing my experience as more of a YMMV.

the Bosch is lying around my parts room (i dunno why i even purchased one in the first place), so it was a no-brainer...

I'd keep your advice in mind and purchase a Denso sooner or later. thanks!

You can usually get Denso sensors at a decent price if you buy them with the Denso part number.  The a/f sensor I have for my car is for a RSX Type S and is usually around $200+ if you buy it from Honda.  When I bought it with the Denso part number from Amazon, it was $99.

I hate that companies do this. Relabel a part and sell it for seven times more

Got my high-flow cat today. A bit confused about EPA regulation though, can I take this to a shop and have them replace it in even though my current OEM cat is still working? Really don't feel like dealing with the bolts after 116k. I live in VA and I'm pretty sure our emissions laws aren't as strict as CA.

Since my current gas mileage its very bad, Some members have suggested i may have a clogged catalytic converter. I wanted to ask you guys for your opinion on what kind of replacement i should get. I plan on getting a TSX header and full 2.25 custom exhaust in the near future so what would be best for this? I live in Florida so emission tests is not a problem. I have an I4 Auto with an OBX muffler in stock piping right now. The options that come to mind are.

1. Replace it with OEM or similar "plug and play" cat.
2. Take the one i have and gut it completely (will i get a CEL?)
3. Replace it with a Test Pipe
4. High Flow Cat

I don't know much about exhausts systems and such so school me!

I used an ebay test pipe on my 04 V6 with no issues.  It was $30 and pretty good quality.  But that was for the third cat... not sure how that would work on yours.

I dont see why it would be different. Except that i only have one Cat in my i4. What are the advantages and disadvantages of a test pipe?

Catalytic converters rob power.  Run a test pipe.  If you're seriously trying to make decent power with your exhaust, consider something a bit bigger than 2.25".  Most guys are running a 3" exhaust on their K's and make good power with them.

Really? The reason i had 2.25in in mind was because if i remember correctly i read in some posts that running a 3" exhaust in the k24 or even 2.5" would cause a loss in power or torque or something in the lower end? something about back pressure or something like that?

Yeah, that's all bullshit.  K's want to breathe and it has been proven over and over again that they respond well to a 3" exhaust.  Of course, you'll also want to have the proper header and intake set up too.  That's where you'll end up spending quite a bit of cash if you really want to make some power.

Well I have a short ram intake, tsx intake manifold, light weight under drive pulleys and that's where I plan to stay with the exhaust being the last piece of the puzzle. I'm not aiming for great power increase and I already have a muffler that I like the sound of, it has a 2.5 inlet so should I just run  a 2.5 custom exhaust and call it a day. Or is half an inch more really worth it?

In that case, run at least 2.5".  That will keep the noise down.  I have a 3" exhaust set up, and it's fairly quiet because I have more than one muffler.  Because it's 3", it flows a lot better.

Will do. Thanks again man.

Tried taking off the cat today in my college apartment parking lot but that didnt go well. Those bitches are tight! Im gonna have to wait until i go home (Miami) this weekend so i can use the BIG tools.

You may need to soak them in PB blaster and get a breaker bar.
