Porsche 911 991 991.2 GT3 Fabspeed Race Manifold

Product description

Designed for competition and all-out racing, track events and off-road use, Fabspeed Motorsport USA Long Tube Race Headers are designed to maximize the power and torque potential of the Porsche 991 GT3, 911R, 991.2 GT3 engine by increasing/ tidy. exhaust flow and exhaust pulses from the flat 6 cylinder heads directly into the exhaust system. This system was designed, developed incrementally by Dyno and maximizes engine power across the entire powerband. Porsche Motorsport engineers and pre-emiminet exhaust companies such as BURNs Stainless LLC were consulted to design the Ultimate GT3 competition slip-on-header system in 321SS.

From the moment we heard that Porsche would be equipping the 991.2 GT3 with the mighty 4.0L engine, we couldn't wait to get our hands on one. As soon as we got under a stunning 2018 Miami Blue GT3, our engineering team immediately went to work adapting our already highly regarded Long Tube Competition Race Header system to maximize the performance of the 991.2's new 4.0L engine. Like the 991.1 GT3, there is no better designed racing header system for the Porsche 991 and 991.2 GT3 available worldwide. All Fabspeed Motorsport Long Tube Race Headers are developed in collaboration with the racing engineers at Burns Stainless LLC Costa Mesa California. Burns Stainless is a global leader and innovator in stainless steel header design, testing and building high-speed headers. The entire system is made of 321L stainless steel with titanium in the 321 alloy for maximum heat tolerance.

BURNS STAINLESS COLLECTORS: Ending our headers are Burns Stainless Collectors that combine high flow and high speed to increase and broaden an engine's torque curve. Our decision to use Burns Stainless entry level collectors was simple, their superior design and Burns Stainless unrivaled 30 years of proven performance in Worldwide Motorsport Competition.
