GReddy is proud to announce the Revolution RS line of exhaust systems. Named for the revolutionary approach to the design and construction of each application, this racing-sport line focuses on performance with an aggressive look and sound. Careful attention to the flow of exhaust layouts and the internal straight-through construction of each muffler and resonator sets this system apart from similar-looking imitators. Updated ultra high-temperature resistant, sound suppression materials of various densities and high-quality TIG-welded 304 stainless-steel provide premium quality at an affordable price.  The Revolution RS is covered by a limited lifetime warranty.

The Revolution RS for the Subaru WRX/STI sedan features full 3.0” diameter piping for superior performance. Dyno test have shown increase in 12hp and an amazing 32ft-lbs of torque. The purposeful single-sided cat-back layout with minimal bends produces a cost-effective, light-weight system. Classic GReddy styling positions the muffler and tip stylishly underneath the right side of 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.
