SMOOTHER EXHAUST FLOW
PERRIN offers this replacement Downpipe for those looking to improve performance on their WRX/STI and are using the vehicle in an off-highway, off-road and/or for competition where the OEM unit won’t suffice.
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 / 2004-2021 STI alike! Gone ar
