The Only Exhaust Thread You Should Ever Post In

[thisaznboi88]

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

[fabulous010]

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.

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

[clapton924]

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

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.
