The Porsche 991 takes the legendary 911 series to the next level. With its flat-six 3.8 liter, sky-high 9000 rpm engine and its tremendous handling, it is considered by many as one of the best supercars for the road and the track. At the same time, many criticize the sound of the stock exhaust system, as it fails to translate the real FEEL this German masterpiece of engineering should deliver for the ultimate driving experience. But there is no need to worry, because our full exhaust system is the solution you were looking for.
Our Valvetronic exhaust system for the Porsche 991 & 991.2 GT3 / RS comes with headers and 200-cpsi sport catalysts in refined stainless T304 steel. The headers, sport catalysts, and the optimized valve-controlled muffler work together in total harmony to deliver a maximum increase in power and a breathtaking sound. Since this system is clearly equipped with racing genes, the sound is accordingly deep in the lower and middle rpm ranges, while being loud and aggressive at higher rpm. With our valve-controlled exhaust system your vehicle truly sounds like a GT Race Car. 
*OPF versions are not available.

All standard tips comes with chrome silver tips.  Other colors are value-added.
