PERRIN offers this replacement J-Pipe for those looking to improve performance on their 2015+ WRX and is using the vehicle in an off-highway, off-road, and/or for a competition where the OEM unit won’t suffice.


Featuring a clever, two-piece design, for easy installation. The adjustable tail section will adapt to OEM and aftermarket Cat-Back exhaust systems. We include an additional O2 sensor behind the turbo to easily mount a Wideband O2 sensor for AFR gauges or future tuning.


Built from CNC mandrel bent 3" tubing and featuring a full stainless-steel catalyst, the PERRIN downpipe features 304 stainless steel for high corrosion and heat resistance up to 1800 degrees Fahrenheit.


Thick .500" CNC cut stainless-steel flanges will not warp and are designed to bolt up to your PERRIN or OEM cat-back exhaust system.


The PERRIN J-Pipe comes with a brushed stainless-steel finish featuring TIG welding for precise, clean welds.


Proper ECU Tuning is required for the safe operation of the engine with this product. Engine performance and fuel economy will also suffer without tuning. Check all local, state, and federal laws prior to purchase and installation.
