Designed for Competition and all out racing, track events and off-road use, Fabspeed Motorsport USA Long Tube Race Headers are engineered to maximize the horsepower and torque bolt-on potential of the Porsche 997 GT3 and 997.2 GT3 engine by increasing/scavenging exhaust flow and exhaust pulses from the flat 6 cylinder heads/ports straight into the exhaust system. This system was designed, incrementally Dyno developed and maximizes engine power all throughout the powerband. Porsche Motorsport engineer builders and pre-eminent exhaust companies like BURNs Stainless LLC were consulted to design the Ultimate GT3 competition slip on header system in 321SS.

Additional engineering news and better quality for 997 GT3 Racers and drivers. Fabspeed Motorsport has worked with many of the very latest 991 GT3 CUP cars and 991.2 GT3 RS cars and a lot of the new cars engineering and breathing insights have been FOCUSED back onto continually improving our 997 GT3 systems across the board. Our engineering team immediately got back to work and adapted certain features our already highly regarded Long Tube Competition Race Header of the new 991.2 GT3 4.0L engine for the 997 GT3. There is no better designed and engineered race header system for the Porsche 997 GT3 available worldwide. All Fabspeed Motorsport Long Tube Race Headers 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. The entire system is built from 321L stainless steel which has Titanium in the 321 alloy for maximum heat tolerance.
