aFe introduces the MACH Force XP dual axle-back exhaust system for the 11-14 Mustang GT V8-5.0L. In recent testing this system produced 18 horsepower and 15 lbs. x ft. of torque. This exhaust is constructed from 3 in. mandrel-bent, stainless steel and is MIG-welded. The system uses high-flow, stainless steel mufflers which improves performance across the power band while maintaining a great tone. To finish off this exhaust are dual 4 in. double wall, 304 stainless steel aFe laser-etched tips. 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..
