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

The Maxflo exhaust replaces the Porsche 996 Carrera rear mufflers with a muffled stainless system and a choice of outlet arrangements. It is intended for a moderate increase in sound compared with the louder Supercup and straight-through bypass alternatives. 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.
