STM Stainless Dual Exit Cat-Back Exhaust for 2022+ WRX

STM Tuned Inc.



We price match!

The STM 2022+ WRX stainless steel dual exit catback exhaust will bolt up to your stock or aftermarket downpipe utilizing existing hangers and includes all gaskets and hardware for a clean and easy install. Available with or without a resonator in the midpipe.

USA made using lightweight .049" wall stainless, the resonated version is 5 pounds lighter than stock and the non-resonated is 9 pounds lighter. This exhaust simply looks and sounds bad ass. We love the clean, stealthy appearance and deep, rich sound - yet it can still be quiet when you need it to be. If you have nosy neighbors, the extra resonator will help - but it's still probably going to wake them every morning on cold-start. Let's be honest, they were complaining about the stock exhaust too!

Love it!

I was driving it here with the resonator and it looks and sounds perfect. Gives a nice healthy crackle now and the exhaust note is deep and rich. Push in the clutch and the car is super quiet if you need to be stealthy. Well done STM.
