Fabspeed Porsche 997.2 GT3 / GT3 RS Long Tube Competition Race Header System (2010-2011)

Designed for racing, track events and off-road use, Fabspeed's Long Tube Competition Race Headers with integral Side Muffler Bypass Pipes are designed to maximize the horsepower and torque bolt-on potential of the Porsche 997.2 GT3/GT3RS engine by increasing exhaust flow from the engine cylinders straight into the exhaust system. This system was designed, incrementally dyno developed and maximizes engine power all throughout the powerband.                                                                                                                          

When the first 997.2 GT3 landed on North American soil, our engineering team immediately got to work and developed a Race Header to maximize the performance of the track weapon. Our original medium tube modular header design was very successful, but we were looking for more power. Consequently, we were approached to enhance a GT3 RS and welcomed the opportunity to refine our long tube header design further. After extensive development, including dyno and track testing of various designs, we've uncovered the correct formula to unlock the maximum performance and exhaust flow from the Porsche 997.2 GT3/GT3RS. There is no better designed and engineered race header system for the Porsche 997.2 GT3/GT3RS available worldwide. The Fabspeed Motorsport GT3 header was developed in conjunction with the racing engineers at Burns Stainless LLC Costa Mesa California. Burns Stainless is a World leader and innovator in stainless steel header design, testing and building high velocity merge collectors.
