Greddy RS-Race Cat-Back Exhaust System

This exhaust system has a simple yet effective formula for increased horsepower, increased torque, along with reduced turbo lag while producing an aggressive exhaust note. This is possible by combining a larger piping diameter with minimal bends to provide an unobstructed exit path for the exhaust gases. 

This is a direct replacement for your factory exhaust system as the exhaust hangers are welded onto the OEM locations. Another benefit is the weight savings due to the 304 stainless steel construction. The RS-Race Cat-Back Exhaust System will include a pair of new gaskets, and new hardware making this exhaust system ready for the installation.
