Fabspeed Sport Catalytic Converter for Porsche 911 Carrera (1976–1989)

This Fabspeed Sport Cat replaces the original converter section of the listed Porsche 911 Carrera exhaust with a 300-cell catalyst assembly. It retains a catalytic element and includes the oxygen-sensor provision, distinguishing it from the resonated European bypass pipe. Based in Fort Washington, Pennsylvania, Fabspeed Motorsport designs exhaust systems, air intakes and ECU tuning for Porsche and other sports cars. Dynamometer testing, road evaluation and racetrack development inform its product range.
