We here at Mach V have always been a fan of the great-fitting parts from Invidia. The 2015-2021 WRX downpipes are no exception. Invidia downpipes will work with the factory cat back or an Invidia cat-back. (Use a donut gasket adapter to mate up to a factory style exhaust.) Each downpipe is made of stainless steel polished to Invidia's signature mirrored finish, with a high-flow cat placed close to the turbo for maximum efficiency. Each J-Pipe exhaust is made with two O2 sensor bungs for the factory sensors and an additional bung for an aftermarket wideband.
Note that custom ECU tuning is required with installation of an aftermarket J-pipe. Also, we cannot guarantee you will not have a Check Engine light due to the aftermarket catalytic converter. If you want to guarantee no Check Engine light, keep your stock J-pipe on the car.
Fits all 2015-2021 Subaru WRX; choose manual or CVT transmission.
Availability note: Supply on Invidia products has been spotty. Please call about product availability before ordering.
