The TurboXS downpipe uses a full 4″ cast bell mouth section on the turbo side, tapering to a 3″ mandrel-bent stainless pipe.
The downpipe is sold with a TurboXS high-flow cat to connect up to your TurboXS cat-back exhaust.
We’ve had a few people inquire about just buying the front half of this downpipe, as a “shorty” downpipe to fit their factory cat section. That’s not going to work; the front half of this downpipe is designed to fit the full 3″ TurboXS cat pipe ONLY.
Fits all 2002-2007 WRX and STI.
