This system is truly unparalleled in sound quality. After over a year and a half of dedicated research and development, we’ve engineered an exhaust experience that must be heard to be believed.

When Porsche introduced the DFI engine in the 991 GT3, many feared it would lack the soul of the legendary Mezger. But with a screaming 9,000 RPM flat-six, Porsche delivered in spades. Still, the factory setup leaves much to be desired when it comes to rawness and that elusive F1-style sound.

At Valvetronic Designs, we’ve crafted a system that elevates your GT3 experience. Featuring 2.5-inch piping, a large stamped cross-section X-pipe, and added loop sections to lengthen the exhaust path, this setup achieves the high-pitch motorsport tone enthusiasts crave. Combine it with our free-flow headers, and your 991 becomes one of the most exhilarating sounding machines on the road.
