Fabspeed Catless Race Headers for Porsche 991 Carrera (2012–2016)

These race headers remove the original catalytic-converter assemblies from the Porsche 991 Carrera exhaust path. Equal-length primaries and a 3-into-1 layout provide a catalyst-free competition configuration with a marked increase in volume. Fort Washington, Pennsylvania, is home to Fabspeed Motorsport. The company engineers sports-car exhaust systems, air intakes and ECU tuning, including Porsche applications, with product development involving dyno, road and racetrack evaluation.
