Notes: The Invidia R400 Gemini single layer quad black tip catback exhaust for your Subaru WRX / STI is among one of the most popular catback exhaust systems available as they make for an excellent upgrade over the OEM exhaust system. The combination of increased piping diameter along with smooth bends relieves the exhaust restriction and turbulence under acceleration which will increase the horsepower and torque. This will also help improve the throttle response and reduces the turbo lag. Don't forget, if you have the stock downpipe/J-pipe, you'll need this adapter from our friends at GrimmSpeed!
