aFe Power MACH Force XP Down Pipe - 335i 2011-2012 L6 3.0L (t) N55

This awesome Mach Force XP Down Pipe produces 14 horsepower and 39 lbs. x ft. of torque at 1900RPM.  The Mach Force XP down pipe is constructed of mandrel bent, brushed 304 stainless steel tubing and flanges and uses all factory mounting locations.  Using a unique resonance chamber to capture sound waves and minimize exhaust "drone", this system produces an aggressive tone on throttle but a smooth sound at cruising speeds without affecting performance. This down pipe is 100% TIG-Welded.

Note: aFe's Down Pipe recommends an aftermarket tuner to clear the check engine light.
