GReddy Revolution RS Cat Back Exhaust 2002-2007 WRX / 2004-2007 STI

Greddy, who are one of the pioneers in high-performance parts for the sport compact community delivers yet again with the introduction of the RS Cat-Back Exhaust System. This exhaust system has primarily been designed to improve sound and performance. Cars with forced induction really respond well to a well-designed exhaust system because when you get smooth mandrel bend combined with larger piping diameter, you are relieving the turbocharger of any restrictions that can be had with the factory exhaust system.

The Greddy RS Cat-Back has been fabricated from high-grade stainless steel materials and features 76mm piping diameter with an 115mm exhaust tip. Exhaust hangers have been carefully welded onto the OEM locations on the piping which means no further alterations will be required to the chassis or rear bumper for fitment.

The RS Cat-Back will come provided with new gaskets, as well as hardware to make this exhaust system ready for installation.
