This MACH Force XP Cat-Back exhaust system for the 2011, 2012, 2013, 2014 Ford F150 3.5L Ecoboost V6 is constructed of 3" into to 3.5" mandrel-bent stainless steel tubing and comes complete with free-flowing muffler, OE style bayonet hangers, band clamps and all hardware necessary for a hassle-free installation. The smooth curves and increased diameter of this exhaust system helps remove restriction and keeps exhaust gas flowing smoothly for increased horsepower and torque. In house testing this system produced +35 horsepower and +39 lbs. x ft. of torque over the stock exhaust system verified by our in house dyno. The system is finished off with a side exit 4-1/2" stainless steel, rolled slash cut tip in wrinkle black or polished for an aggressive style. This MACH Force XP uses all factory mounting locations providing stability and a hassle-free installation. High quality OE-style flange and premium band clamps are used for a complete 360-degree sealing surface eliminating leak paths. A straight-through designed, free-flowing stainless steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque. OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time. This MACH Force XP exhaust system is designed with a 3" to 3.5" stepped design which increases exhaust velocity and creates a broader torque curve throughout the RPM range.
