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

STM Tuned Inc.



We price match!

The STM 2022+ WRX stainless steel single 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.

The single exit stainless design is a great lightweight option without the titanium price tag. This exhaust weighs in at 20.7 pounds - 16.3 lighter than the stock catback at 37 pounds. The single exit stainless gave us a deep exhaust note with a few burbles and crackling. Sounds great in the car and gets very quiet when you push in the clutch if you need to be stealthy. It's pretty rowdy on cold-start.
