aFe is proud to introduce an all new Mach Force-Xp cat-back exhaust system for the 2015-2016 Ford Mustang EcoBoost with the I4-2.3L (t) engine. In recent testing, this system produced +16 horsepower and +17 lbs. x ft. of torque on our in house dyno. This cat-back exhaust system utilizes 3” into 2-1/2" tubing with a clamp-on reduction tube to fit the stock connections. Remove them and combine with the aFe Power Twisted Steel down-pipes (P/N: 48-33017-HC or 48-33017-HN) for added flow and performance. This system incorporates dual, high-flow mufflers to improve performance across the power band while maintaining an aggressive sound. To finish off the exhaust, dual 4" diameter high-luster polished 304 stainless steel tips are included. This system includes hardware for a hassle-free installation.
