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.

  1. Absolute bargain and 2nd best single exit exhaust out there!

    By SSJ B October 16, 2022

    Installation was extremely easy, and I absolutely love the aggressive fitment. Tomei still sounds the best for single exits for the VA chassis. However, I eanted something a little less common and this Greddy sounds fantastic and really brings out that UEL subie rumble while being close to half the price of the Tomei. Theres a little bit of drone but nothing unbearable imo.

  2. Absolute steal for what you get!

    By SSJ B October 11, 2022

    Installation was a breeze (highly recommend grimmspeed 3 inch adapter for stock DP) and absolutely love the aggressive old school JDM look this exhaust gives. In cabin sounds phenomenal and really brings out the deep Subie rumble for STI's. There is slight drone at 2.5-3K RPM but its really not as bad as I thought it would be being non resonated. Lastly, the tip is interchangeable so you can stick with the stainless finish or upgrade to a titanium burnt tip which is awesome! Overall extremely happy with this Greddy exhaust and it is an absolute bargain for what you get, 10/10.
