Product details
aFe introduces the MACH Force XP axle-back exhaust system for the 05-09 Mustang V6-4.0L. In recent testing this system produced 9 horsepower and 11 lbs. x ft. of torque. This exhaust is constructed from 2.5 in. mandrel-bent, stainless steel and is MIG-welded. The system uses a high-flow, stainless steel muffler which improves performance across the power band while maintaining a great tone. To finish off this exhaust is a 3.5 in. rolled edge, 304 stainless steel aFe laser etched tip. This exhaust uses all factory hanger locations for a hassle-free installation. No modifications necessary. All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
