The MACH Force XP exhaust system is constructed of 3.0” mandrel bent, stainless steel tubing and retains the use of all factory hanger locations for hassle free installation. As tested by aFe this exhaust system produced 12HP and 17 ft. lbs. of torque over stock!
For increased performance across the power band and a great tone the system uses a high flow 18” transverse muffler with 3" diameter tubing. The finishing touch to the exhaust is dual, double- wall, angle cut stainless steel tips. aFe offers 328i customers the choice of either black or polished twin tips with a laser etched aFe logo.
