Grail: high-end valved exhaust systems

Grail designs valved exhausts for exceptional sports cars: the Porsche 911 (992) Carrera, Carrera S, Carrera 4, GTS and Turbo S, and the Audi RS3 (8Y). Rear silencers and GPF-back systems, in black or matt black.

Adjustable sound

The controlled valves let you choose between a discreet everyday sound and a full sound on the road. Select your vehicle to see the system made for it.
