AMS Catback Exhaust | EVO X

Filed under Exhaust

ams exhaustThe AMS EVO X Racing Series Cat-Back Exhaust System is a no-nonsense, all business exhaust system designed to make the most power and shed serious weight off your EVO X. Our exhaust features mandrel bent piping for the best exhaust flow.  This system does not have any restrictions like other popular exhaust systems that “neck down” and hurt performance.

    The new O2 downpipe combo looks awesome. It’s cast so you don’t have to worry about it cracking or welds busting loose. I prefer the dual version of this exhaust but the single does save some weight.

    AMS really offers some of the best quality products. They just released a new O2 downpipe combo which claims 30hp if I remember correctly.
