STM*SEE DETAILS
2022+ Subaru WRX Catted Downpipe/J-Pipe by STM
The STM 2022+ Subaru WRX catted downpipe is now available! Also called a j-pipe or pipe, this part connects from the turbo to the cat-back exhaust and is capable of flowing 850 horsepower. A faster spool and increased power throughout the entire power band make this piece a must-have to take your car to the next level!
This downpipe fits with the stock exhaust or aftermarket cat-back systems that bolt to the factory locations. We include new 2-bolt gaskets and hardware, but if you need to replace the turbo gasket, we recommend the GrimmSpeed Turbo to Downpipe Gasket (026003) Two o2 bungs are included for the front and rear oxygen sensors, and stainless hardware is provided for the ground strap. The factory downpipe weighs 24.7 and the STM downpipe weighs 16.2. You'll save 8.5 pounds, gain power, have a fully stainless exhaust that won't rust out and it sounds great!
