This new MACH Force XP exhaust system is for the 2012-2017 BMW 328i (F30) with the N20 2.0L turbo engine. In recent testing this system produced 12 horsepower and 17 lbs. x ft. of torque. This exhaust system is constructed from 3.0” mandrel bent stainless steel and is MIG-welded. The system uses a high flow 18" transverse muffler with 3" diameter tubing which improves performance across the power band while maintaining a great tone. To finish off this exhaust are dual double wall resonated angle cut gloss black 304 stainless steel tips. The factory actuator drive is retained with the aFe exhaust so that a check engine light does not occur. This exhaust uses all factory hanger locations for a hassle free installation. No modifications necessary. Note: Does not fit vehicle with N26 engine. N26 engine is SULEV (super low emission) version of N20

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

Simple Installation:
All systems use factory mounting locations providing stability and hassle-free installation.

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

Very Aggressive Tone:
A free-flowing muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque.

See Part Number 49-36329-B for more Moderate tone
