The PERRIN Performance 3in Catted downpipe features a divorced wastegate and cat which will separate the exhaust gas exiting the down pipe, creating a smoother exhaust flow, resulting in more horsepower and flow. The Downpipe is constructed to 304 stainless steel 36-inch mandrel bend tubing and bolts up to any stock replacement cat. This downpipe has a unique design of using a rear slip joint so the downpipe can be used on any EJ turbo powered car. Gone are the days on not having a properly sealed exhaust system, this downpipe will allow you to ensure the proper lengths are had with whatever exhaust system you are using.
Fits all 2002-2014 Subaru WRX, and 2004-2022 WRX STI.
