JDM vs USDM STi exhaust
Are there any differences? I want to buy a JDM STi exhaust for the stealth look and lose one cat, wondering if it is any different from the USDM one.

FYI The USDM STi exhaust only has 2 cats (no pre-cat).

If all you want to do is remove 1 cat, just buy an aftermarket catless downpipe that mates to the rest of the stock turboback exhaust. Or just get a TurboXS Stealth-back with 1 cat and keep your original muffler section.

thanks for the info. the jdm has 1 cat so i guess it's even better than the USDM one. i wanted to get this instead of a downpipe because 1) it looks stock 2) it will cost less than a downpipe

ok after verifying this with bikerboy in another thread the JDM STI has a twinscroll turbo which means it has a different flange on the downpipe and hence will not fit on a USDM STI turbo
