Welcome to the Valvetronic Designs valved sport exhaust for the Porsche 997. Designed from the ground up, this system gives your 997 a truly unique voice, unlike anything else on the road. Race-bred equal-length headers, a free-flow X-pipe and valved side mufflers combine for an F1-inspired note that unlocks the emotion hidden in this platform.

Valves open delivers an aggressive, motorsport-quality sound; valves closed cuts volume significantly and strips away unwanted frequencies for daily comfort. This is a complete setup only — not an axle-back or partial system — ensuring perfect harmony between flow, tone and function.
