Perrin Divorced Catted Downpipe - 2004+ Subaru STI | 2004-2014 WRX
The PERRIN Performance Catted Downpipe features a divorced wastegate and cat which will separate the exhaust gas exiting the downpipe, creating a smoother exhaust flow, thus resulting in more horsepower and torque.
The downpipe is constructed of 304 stainless steel 3-inch mandrel-bent tubing and bolts up to any stock replacement cat-back or stock unit. PERRIN Performance has created a unique design that utilizes a rear slip joint so this downpipe can be used on 2002–2014 WRX / 2004-2020 STI alike! Gone are the days of 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!
