The Grail stainless steel upgraded exhaust system for the 991.1 Porsche 911 GT3 and GT3 RS produces an incredible and unmistakeable sound. It's the sort of transformation that gives you goosebumps every time you start your engine.

The use of highly effective silencers enables maximum volume and wonderful engine sound. When the valves are closed, the exhaust gases flow through the rear backbox to allow the system to remain quiet for daily driving. When the valves are open, the rear backbox is completely bypassed for maximum noise!

Flow has been improved over the factory system due to a larger pipe diameter of 3 inches (76mm).

SPECIFICATION

- Hand-crafted in Germany from high-quality L304 stainless steel
- 76mm exhaust pipe diameter
