aFe BMW M3 2007-2011 V8-4.0L E90/92 Cat Back Exhaust

This awesome Mach Force XP Cat-back exhaust system produces 13 horsepower and 16 lbs. x ft. of torque. This system is constructed of 3" tig-welded mandrel bent, polished 304 stainless steel tubing and uses all factory mounting locations for an easy 1hr install time.  This system uses a unique dual 3" torque chamber designed for a broad power curve and to cancel high frequency sound waves producing an aggressive tone on throttle with a smooth sound at cruising speeds.  This system is 20lbs lighter than the factory exhaust system and is finished off with stunning 3 1/2" polished 304 stainless steel dual tip.  This is simply the most sophisticated exhaust system for the M3 on the market designed and engineered for flawless performance.

All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
