Fabspeed Rennkraft Modular Headers for Porsche 992 GT3

Select sport-catalyst sections, bypass sections or both with the Rennkraft modular GT3 headers. V-band joints make the matching sections exchangeable when both configurations are purchased. Fabspeed Motorsport designs performance exhaust systems, air intakes and ECU tuning in Fort Washington, Pennsylvania. Porsche and other sports-car applications are developed through dyno testing, road evaluation and racetrack work.
