aFe POWER is proud to introduce a MACH Force-Xp cat-back exhaust system for the Ford Mustang with the L4-2.3L (t) EcoBoost 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 gloss black 304 stainless steel tips are included.  This system includes hardware for a hassle-free installation.

Aggressive Sound:
Dual free-flowing mufflers are used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque.

Y-Pipe w/Mitered Split:
This MACH Force-Xp cat-back includes a y-pipe with a mitered split which eliminates dead space that can cause turbulence and hinder flow that formed collectors are prone to produce.

Leak-Free Seal:
High quality band clamps are used for a complete 360 degree sealing surface.

Dual 304 SS Tips:
Finishing off this unique exhaust system are dual, aFe laser etched, 5" gloss black 304 stainless steel tips for an aggressive style.

Removable Reduction Pipes:
Reduction pipes are included to fit the factory exhaust. They can be removed to combine with the aFe Twisted Steel down-pipes for increased flow and performance (P/N: 48-33017-HC or 48-33017-HN).

Fitment Note:
This system only fits coupe models
