The Only Exhaust Thread You Should Ever Post In

[Jeff Likes Bagels]

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.

Just like the other threads, I have taken the MULTIPLE threads that all have the same fucking topic and lumped them into one thread.  I have done this because there is no reason to have more than one thread for one topic.  Any more new threads that are created will be deleted and a temporary ban may be considered for not following the forum's rules.  Please post any questions, comments, or advice in this thread instead of creating a new thread from now on.

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.

[HEcreated487]

^^ 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??

[Icebox]

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.

[HEcreated487]

^^ 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 

[Icebox]

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.

[timot_one]

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.

[linguinipenguini]

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

[CrackerTeg]

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
