STM Evo X Stainless Cat-Back Exhaust

Juan Serrano (Irving, TX, US)
STM catback

Great sounding exhaust and great fitment

Benjamin Beaird (Columbus, GA, US)
Best Evo exhaust hands down IMO

The build quality is impeccable. It's honestly the ONLY exhaust that I wanted on my evo X. Back when I had my Evo 8, you guys were just starting to make these exhausts in aluminum.

Anthony Maldonado (Philadelphia, PA, US)
Sounds Awesome

Probably best sounding exhaust ever, wasn't a big fan of the smaller tip initially but after seeing fitment first hand, i was turned around and really impressed. You can clearly hear turbo spool now through the exhaust. Wish I bought this system from the start.

Garrett (Glenside, PA, US)
Great exhaust!

There are so many companies out there now making evo x exhaust systems. I was overwhelmed at first. I was on a mission to find a single exit system that was built well and sounded great. This exhaust does just that and more.
