Valvetronic Designs Valved Exhaust System for Porsche 991 GT3 / GT3 RS 2014-2019

Overview:

This exhaust is on another level when it comes to sound. After more than a year of testing and refinement, the result is an experience you feel the moment the engine fires. When Porsche moved to the DFI engine in the 991 GT3, a lot of people worried it would lose the character of the Mezger. Then it revved to 9,000 RPM and proved everyone wrong. The problem is the factory exhaust still holds the car back from the edge most GT3 owners want.

Valvetronic Designs built a system that unlocks that missing emotion. It uses 2.5” piping, a large stamped X-pipe, and extended loop sections to stretch the exhaust path and create that high-pitch motorsport note. Pair it with the free flow headers and your 991 turns into one of the most exciting sounding cars you can drive.
