Fabspeed Primary Sport Catalysts for Porsche 955 Cayenne Turbo / Turbo S (2002–2007)

These Fabspeed Primary Sport Catalysts replace the factory primary converters on the 2002–2007 Porsche 955 Cayenne Turbo and Turbo S. The assembly retains HJS catalytic cores while revising the flow path, and should be matched to the Turbo-specific exhaust rather than a naturally aspirated Cayenne. From Fort Washington, Pennsylvania, Fabspeed Motorsport develops Porsche and other sports-car exhausts, intakes and ECU software through dyno testing, road use and racetrack evaluation.
