The Revolution RS for the Mitsubishi EvoX features full non-tapered 3 diameter piping. Perfect to be used with optional 3 downpipe. The lightweight single sided cat-back exhaust shaves over 20lbs off the car. The design still maintains good sound levels and quality with a large resonator and extra-long RS muffler. Classic GReddy styling positions the muffler and tip stylishly underneath the car while matching the profile body-lines perfectly. Like all GReddy Revolution RS systems, the exhaust is made from fully hand-welded 304 Stainless-Steel and carries a Limited Lifetime Warranty
