Fabspeed Cat Bypass Link Pipes for BMW M3 E46 (2000–2006)

Fabspeed competition link pipes replace the E46 M3 catalytic-converter section with a straight-through arrangement. Resonators help shape the exhaust note, but these remain catalyst-removal components rather than sport converters. Fabspeed Motorsport, based in Fort Washington, Pennsylvania, develops exhaust systems, air intakes and ECU tuning for Porsche and other sports cars through dynamometer, road and racetrack evaluation.
