HS15STIGM4SB
The Invidia R400 Gemini Single Layer Quad Black Tip Cat Back Exhaust for your Subaru WRX / STI is among one of the most popular cat-back exhaust systems available as they make for an excellent upgrade over the OEM exhaust system to improve the performance and the sound. The combination of increased piping diameter along with smooth bends relieves the exhaust with restriction and turbulence under acceleration which will increase the horsepower, the torque, all while improving the throttle response and reducing the turbo lag.
The black version of the hottest exhaust on the market.
