Fabspeed Sport-Cat Muffler Bypass for Porsche 930 Turbo (1976–1989)

This single-outlet 930 Turbo assembly combines a muffler bypass with a high-flow sport catalyst. It changes the rear exhaust layout while retaining a catalyst core, rather than supplying a conventional silencer. Based in Fort Washington, Pennsylvania, Fabspeed Motorsport designs exhaust, intake and ECU-tuning products for Porsche and other sports cars. Development includes evaluation on a dynamometer, on the road and at the racetrack.
