Fabspeed’s Long Tube Competition Race Header System for the Porsche 991 GT3 / GT3 RS / 911 R will get you out of the corner fast and maximize your pulling power on the straights! Designed for track and off-road use, our Long Tube Competition Race Headers with Side Muffler Bypass Pipes provide maximum exhaust flow from the engine cylinders straight into the exhaust system.
There is no better designed and engineered Long Tube Competition Race Header System for the Porsche 991 GT3 / GT3 RS / 911 R available worldwide. Our comprehensive system is built to optimize the Porsche 991 GT3 / GT3 RS / 911 R engine’s exhaust flow for a significant power bump.
We developed our headers to make power with and without an ECU Tune. While the hardware made significant gains a
lone, we found its full power potential was realized when combined with our proprietary tune. As tested on a GT3 RS, our Long Tube Competition Race Header System with ECU Tune adds 38 whp and 26 ft/lbs of torque at 7650
RPM. Further down the rev range, our Header System gives you major mid range grunt: 24 whp and 28 ft/lbs of torque at 4500 RPM. Without the ECU Tune, you can expect solid gains of 24 whp and 16 ft/lbs at 7650 RPM and 23 whp and 26 ft/lbs at 4500 RPM.
We were graced with a freshly delivered ultraviolet purple GT3 RS for hardware optimization. Our Long Tube Competition Race Header System added 24 whp and 29 ft-lbs of torque at 4400 rpm and 21 whp and 14 ft-lbs of torque at 8000.
After extensive development and refinement of various tested header protoypes on our in-house Dynojet, we’ve unlocked the maximum performance from the Porsche 991 GT3 / GT3 RS / 911 R.
We've happily partnered with Burns Stainless to maximize the performance of our Long Tube Competition Race Headers. They were engineered using a proprietary X-design parametric computer program and combine high flow and high velocity to increase and broaden an engine's torque curve all the way to the horsepower peak and beyond. Featuring the highest quality fabrication and TIG-welding, each Burns merge collector is completely hand finished inside for a smooth, non turbulent merge of exhaust gasses for maximum power gains.
Constructed from T304 stainless steel C.N.C. mandrel-bent tubing from our in-house Unison mandrel bender.
To provide the ultimate track solution for the 991 GT3 / GT3RS / 911 R, we are now utilizing premium Helical valves. We chose to use Helical Valves on our 991 GT3 / GT3 RS / 911 R track exhaust systems for their unprecedented quality - which have been proven by many OEM manufacturers such as McLaren, Ferrari, Lamborghini, and many more.
