DC2R exhaust system

[andreewvoo]

JDM and AUDM catback is the same LENGTH. Not too sure if the AUDM cat will fit the J's B-pipe, unless you cut the AUDM cat and flange it so that it fits the Catback. But yes, you cannot run JDM cat with AUDM header. The AUDM header outlet is tiny compared to say a Toda header outlet.

Sorry guys but reading into forums i get alot of people sayubg AUS headers does not fit JDM cat..

lol. i have JDM headers on my car, why does my AUDM cat bolt up to it? if a AUDM cat bolts up to a JDM header then no doubt JDM cat would do the same

So i wouldn't need to mod the header or cat its just a bolt in job?

[SuperJDM.]

i would think so yes. let tai confirm it though

If the catback exhaust is a jdm branded one, then you need a JDM cat +jdm dc2r headers
9 as a bolt on ) or you get a custom cat to suit the headers/catback

But if the catback exhaust is custom then the b piping can be modified to suit the cat/headers.

But to be honest you are better off getting a new after market cat as the cat itself wil be 10+ years old.

So ur JDM headers bolted on to the AUDM Cat? I brought JDM dc2r headers and wondering if they do... or do i have to buy a jdm cat.

If you change any section of your audm exhaust system to a jdm part, you need to either get some custom work done, or replace the rest of the system with jdm parts. The only piece that is excluded from this is the axle back which is the same on the audm and jdm exhaust system.

^^I'm not sure how you got the 5zigen headers to fit. Is 5zigen an American brand? That's the only way I could see it working

Hes talking about his EM1 with B16 so its not relevant

Well I have literally tried to do that exact thing (5zigen header to audm cat on b16 em1) and it DID NOT work. Interested to hear if there is more to the story
