Clarification about aftermarket Header and Catalytic Converter for DC2R

Well then no one can help you until you confirm it.

OK confirmed, my car has not Cat. Thats why it so damn loud and so much drone!

My eventualy aim is to get some J's Racing Headers - Toda is too expensive, and I want some shiny ones for some bling in the bay.

So what are my options now? I could get an OEM cat, then get a JDM cat when I get headers, or is it possible to get a JDM cat to fit now, so that I save money in the long run?

JDM DC2R Cat or AFtermarket brands to suit JDM DC2R headers will not fit your AUDM DC2R headers.

your best bet is to find a audm DC2R Cat for the time being until you get the rest of the system.

If you are getting aftermarket headers and using aftermarket exhaust it's best to get an aftermarket more free flowing CAT.

thanks a lot. will any exhaust shop be able to provde a cat for JDM headers or is it a specialist ting?

They can custom weld up something that will fit.

awesome thanks for your help

JUST BE CAREFUL THE shops don't cut up your mega dollar exhaust system in the process.

sorry i should have noticed this before, but i didn't.

it is impossible for you to have a stock AUDM DC2R header and AUDM DC2R cat mated to the JDM catback without chopping up the exhaust.
so going by the assumption that the exhaust hasn't been chopped, then yes a test pipe or shorter cat must have been installed in the process.

this is also going by the assumption that the exhaust shop that did the work, didn't actually chop up the header (which i've witnessed) and most exhaust shops won't be able to weld titanium anyway.



just go for the toda header man. i'm using both the J's Racing header and 60RS catback, will have to wait till i get it tuned, but I can put money down that Toda will be the better header tuned or running stock ecu. it's not cheap, but save up that little bit longer and it will be worth your wait.

The car came with a fujitsubo exhaust, and it had not been cut up, so yeah a test pipe has been installed.

If in the meantime, if I get an AUDM cat from a member on this forum, will an exhaust shop be able to make it fit, by cutting the test pipe and putting the cat in?

OK i ve just been told that JDM and AUDM cat back is the same, just that the JDM header is longer, thus needing a cat to be shorter. So if im running AUDM headers, AUDM cat should be fine?

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.

awesome. Well I need a cat, so Ill just get an aUDM one and get it to fit for the time being, then buy some Toda (only if secondhand) headers or J's Racing headers with a JDM cat later
