Valvetronic Valved Sport Exhaust System - Stainless Steel (POR.991.GT3.VSES.BR) - 2014-2019 Porsche 991 GT3 / GT3 RS
The Valvetronic Designs Valved Sport Exhaust System unlocks the full motorsport character of the Porsche 991 GT3 and GT3 RS. Porsches 9,000 RPM DFI flat-six already delivers one of the greatest driving experiences ever built, but the factory exhaust leaves enthusiasts wanting more rawness, more pitch, and more emotion. After extensive research and development, Valvetronic Designs engineered a system that transforms the 991 GT3 into an F1-inspired symphony worthy of the chassis and engine behind it.
Constructed from premium T304 stainless steel, this full valved exhaust system features 2.5 inch piping, a large stamped cross-section X-pipe, and strategically engineered loop sections that lengthen the exhaust path to create the sharp, high-pitched motorsport tone enthusiasts crave. With the valves open, the GT3 delivers a raw, race-inspired scream that builds relentlessly to the 9,000 RPM redline. Close the valves and the system becomes refined and comfortable enough for long-distance cruising and everyday driving.
Performance & Engineering
Designed specifically for the 991 GT3 platform, this exhaust system improves exhaust harmonics and sharpens the sound profile of the naturally aspirated flat-six while maintaining factory-like drivability and valve operation. The large X-pipe configuration and added loop sections create an exotic RSR-inspired tone that dramatically changes the character of the car without compromising comfort when the valves are closed.
