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 991.2 GT3 4.0L 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.                                                      

From the moment we heard Porsche was going to equip the 991.2 GT3 with the all mighty 4.0L engine, we couldn't wait to get our hands on one. As soon as we got underneath a stunning 2018 Miami Blue GT3, our engineering team immediately got to work and adapted our already highly regarded Long Tube Competition Race Header System to maximize the performance of the new 4.0L engine of the 991.2. Just like the 991.1 GT3, there is no better designed and engineered race header system for the Porsche 991.2 GT3 available worldwide. All Fabspeed Motorsport Long Tube Competition Race Header Systems are 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.
