Valvetronic Designs Subaru FA20 WRX Valved Sport Exhaust System

The Subaru WRX has always been about excitement, a car that delivers raw performance and a unique driving experience in a package that has become iconic among enthusiasts. The FA20 turbocharged engine has incredible potential, but the factory exhaust system does not allow it to truly shine. At Valvetronic Designs we set out to deliver an exhaust solution that unlocks the full sound character of this platform while providing the flexibility modern drivers demand.

Purpose-Driven Engineering

This exhaust is available in both high quality T304 stainless steel and our burnt grade 5 titanium, giving owners the choice between two uncompromised materials. Larger piping size improves flow, reduces back pressure, and sharpens throttle response, while the inclusion of electronic valves provides seamless flexibility. With valves closed the system keeps the car composed and quiet enough for daily use, while valves open reveal an aggressive and raw tone that fully highlights the signature Subaru rumble. Beautifully finished exhaust tips complete the look, ensuring that performance is matched by aesthetics.
