These headers are made to order. Our "In Stock" status does not include build time. Actual delivery time can be 1-3 weeks.
Add 19 horsepower and 13 lb/ft of torque while reducing weight.
Designed for racing, track events, and off-road use. Fabspeed's long tube race headers are designed to maximize horsepower and torque potential by increasing exhaust flow and pulses from the headers straight into the exhaust system.
This system was designed and incrementally dyno developed to maximize engine power throughout the entire power band.
Porsche Motorsport engineers and legendary exhaust companies like BURNs Stainless were consulted to design the ultimate GT3 slip on header system.
From the moment Fabspeed heard Porsche was going to equip the 991 GT3 with the all mighty 4.0L engine, they couldn't wait to get our hands on one.
As soon as we they underneath a stunning 2018 Miami Blue GT3, their engineering team immediately got to work and adapted their already highly regarded long tube header system to maximize the performance of the new 4.0L engine of the 991.
Fabspeed claims there is no better race header system for the Porsche 991 and 991.2 GT3 available worldwide.
All Fabspeed Motorsport long tube headers are developed in conjunction with the racing engineers at Burns Stainless in Costa Mesa CA.
Burns Stainless is a World leader in stainless steel header design. They are experts in testing and building high velocity merge collectors.
This entire system is built from 321L stainless steel which has titanium in the 321 alloy for maximum heat tolerance.
