Complete high-performance exhaust solution for the E90/92/93 M3; includes Maxflo Performance Exhaust System, Secondary Catbypass X-Pipe, 200-cell HJS Primary Sportcats, and an ECU Upgrade.                                                                                      

Fabspeed's E90/92/93 M3 Performance Package replaces the restrictive OEM rear mufflers for a deeper, throatier exhaust note and improved power and throttle response.  The included Secondary Catbypass X-Pipe replaces the redundant factory catalytic converters with a high-flowing x-pipe section which increases sound and power.  Lastly, the heavy and restrictive factory primary cats are replaced by Fabspeed's high-performance 200-cell HJS Sport Catalytic Converters for increased power, sound, and emissions compliancy.

Ensure maximum power gains with the optional ECU Upgrade which optimizes the air/fuel ratios, timing, and more in order to take full advantage of the upgraded exhaust components.
