aFe power introduces the MACH Force-XP cat-back exhaust system for the 2011-2013 BMW 335i (E90/E92) with the L6-3.0L Turbo N55. This system is constructed from 100% TIG-welded, mandrel bent, 304 stainless steel 3" into dual 2-1/2" tubing and incorporates a mitered merge for optimum flow. The smooth transition bends allow for low turbulence, increasing horsepower, torque and improved throttle response. In testing, the cat-back exhaust system produced a max gain of +11 horsepower and +17 ft. lbs. of torque verified by our in house dyno* (tested on 2011 BMW 335i N55). Included in this exhaust system are dual high flow transverse mufflers for increased flow and performance across the power band while maintaining a great tone. To finish off this system are dual aFe laser etched, 3-1/2" black 304 stainless steel tips for an aggressive style.

Aggressive Sound:
This system includes dual free-flowing transverse mufflers to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque.

Mitered Split:
This system utilizes a mitered split to eliminate dead space that can cause turbulence and hinder flow.

304 Stainless Steel Construction:
This system is constructed of durable mandrel bent 304 stainless steel tubing for maximum performance, corrosion resistance and strength, eliminating cracking.

Simple Installation:
This MACH Force-Xp cat-back exhaust system uses factory mounting locations providing stability and a hassle-free installation.

Leak-Free Seal:
High quality OE style flanges and band clamps are used for a complete 360 degree sealing surface.
