Designed to target competitive racers, but also offer an economical option for budget-mined tuners, the Greddy Performance Products RS-RACE exhaust line is engineered for absolute performance at a minimal price point. GPP engineers utilize proven, compact, high-flow straight-through, Racing Sport muffler canister and extra large 304 stainless-steel mandrel-bent tubing; 80mm (3.14‚Äö√†√∂‚àö¬®) diameters for turbocharged vehicles and 76mm (3.0‚Äö√†√∂‚àö¬®) normally-aspirated race applications. The RS-RACE systems offer our most aggressive sound quality. To further maximize performance enhancements, weight-saving details, like: simplifying the layout and lightening-up the exhaust flanges and mounting hangers are also considered. The RS-RACE even features our proven removable Tri-bolt tip mounting system to allow for customizing the systems with a variety of optional Titanium or Stainless-steel tips and unique large diameter RS silencers to further control sound emissions.
