These headers are built to order. Our "In Stock" status does not include build time. Actual delivery time can be 1-3 weeks.
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 horsepower and torque. Increasing exhaust flow from the engine cylinders straight into the exhaust system.
This system was designed and dyno developed to maximize engine power throughout the entire power band.
From the moment Fabspeed heard Porsche was going to equip the 991.2 GT3 with the all mighty 4.0L engine, they couldn't wait to get their hands on one.
As soon as they got underneath a stunning 2018 Miami Blue GT3, their engineering team immediately got to work and adapted an already highly regarded long tube competition race header system to maximize the performance of the new 4.0L engine.
Just like the 991.1 GT3, Fabspeed feels there is no better race header system for the Porsche 991.2 GT3 available.
All Fabspeed long tube competition race headers are developed in conjunction with the racing engineers at Burns Stainless LLC in Costa Mesa California.
Burns Stainless is a World innovator in stainless steel header design. They spend countless hours testing and building high velocity merge collectors.
BURNS STAINLESS COLLECTORS:
Bringing our headers to an end are Burns stainless collectors which combine high flow and velocity to broaden an engine's torque curve. The decision to utilize Burns Stainless slip on collectors was easy.
- GT3 header system was engineered with Burns stainless proprietary X-design parametric engine/ exhaust design computer program
- Completely hand finished inside for proper flow and maximum power gains
- Motorsport proven and adopted by NASCAR engine builders along with world championships in Indycar Racing, Formula Atlantic, ALMS, FIA-GT, and Grand Am. Burns stainless is the very best!
