aFe POWER MACH Force XP X-Pipe for the BMW E90, E92 and E93 M3 produced 27 HP and 50 lbs. x ft. of TQ. Constructed from TIG-welded, 2-1/2 IN mandrel bent, 304 stainless steel tubing. It uses dual, high flow, 300 cell catalytic converters for maximum flow providing an astonishing low end torque improvement. While developing this system, we ensured that this item not only increased performance but delivered a powerful and aggressive tone. Incorporated is an X-Pipe balance tube, which equalizes and evenly distributes exhaust pulses for increased performance across the power band. Dual resonators are also used to absorb high pitch sound decibels, minimizing exhaust drone. This item is compatible with the OE muffler or aFe cat-back exhaust systems (49-36311-P, 49-36311-C, 49-36312-P, 49-36312-C, 49-36304 and 49-36305). No modifications required. Uses all factory hanger locations for a hassle free installation.
