Fabspeed Supercup Cat-Back for Porsche 996 Carrera (1999–2004)

Two compact resonators replace the larger original mufflers in the Fabspeed Supercup system for the Porsche 996 Carrera. This track-oriented rear exhaust gives substantially more volume than Maxflo while allowing the compatible catalyst section to remain. 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.
