The Revolution RS for the 2011-14 Subaru WRX/STI sedan features full 3.0 diameter piping, allowing a more free-flowing exhaust which provides superior performance.

The resulting benefit is a cost-effective, light-weight system that improves flow and performance. Classic GReddy styling positions the muffler and tip stylishly underneath the right side of the car while matching the profile body lines perfectly. All GReddy Revolution RS systems are fully hand-welded 304 Stainless-Steel and carry a Limited Lifetime Warranty.
