2022+ Subaru WRX Axle-Back Exhaust by STM
The STM axle-back exhaust/muffler delete for the 2022 Subaru WRX bolts directly in place of your stock muffler and weighs 15 pounds less than stock. Beautifully crafted in the USA, the STM axle-back features a mandrel-bent tube and tig welded flanges with polished, dual 3.5″ slanted, burned blue tips. All new mounting hardware is included along with two Remflex graphite gaskets for a leak-free install.
This will give you that classic low rumble on idle with a nice growl at higher rpm. Sounds great in the cabin, no droning and it even gave us a couple of pops and burbles from an otherwise stock WRX.
