Valvetronic Valved Sport Exhaust System with Free Flow Race Headers - Stainless Steel (POR.991.GT3.VSES.FFH.BR) - 2014-2019 Porsche 991 GT3 / GT3 RS
The Valvetronic Designs Valved Sport Exhaust System with Free Flow Race Headers unleashes the full motorsport potential of the Porsche 991 GT3 and GT3 RS. Porsches naturally aspirated 9,000 RPM DFI flat-six already delivers one of the most emotional driving experiences ever created, but the factory exhaust system leaves much of the sound restrained. After extensive research and development, Valvetronic Designs engineered a complete exhaust and race header package that transforms the 991 GT3 into a true RSR-inspired machine with sharper tone, more aggression, and unforgettable F1-style sound.
Constructed from premium T304 stainless steel, this system features full 2.5 inch piping, a large stamped cross-section X-pipe, engineered loop sections, and free flow race headers designed to maximize exhaust flow and sharpen harmonics. With the valves open, the GT3 produces an uncompromising motorsport scream with aggressive upshift crackles and a relentless crescendo all the way to the 9,000 RPM redline. Close the valves and the system remains refined and comfortable enough for daily driving and long-distance cruising.
Performance & Engineering
Designed specifically for the Porsche 991 GT3 platform, this exhaust system and race header package improves exhaust scavenging, increases flow efficiency, and dramatically sharpens the naturally aspirated flat-six sound profile. The large X-pipe and added loop sections help generate the crisp, high-pitched motorsport tone enthusiasts associate with Porsche RSR race cars and Formula-inspired exhaust acoustics.
