Fabspeed Sport Catalysts for BMW M3 E46 (2000–2006)

Fabspeed sport converter assemblies replace the E46 M3 factory catalytic converters with HJS 200-cell cores. The parts change the catalyst section while retaining catalytic elements instead of using a plain bypass pipe. Fort Washington, Pennsylvania is home to Fabspeed Motorsport, whose exhaust, intake and ECU tuning development for Porsche and other sports cars includes dynamometer testing and road and track evaluation.
