    More Power and Better Performance. Installing AFE's Mach Force-XP 3" Axle-Back Exhaust System on your 5.0-liter Coyote Mustang is a great way to increase its power and performance. By replacing the restrictive factory mufflers with a pair of high flow straight-through mufflers, this Mach Force-XP Axle-Back will significantly improve the exhaust flow of your V8 powered Mustang, in comparison to the original stock exhaust system. After installation of this Axle-Back on a 2011-2014 GT you will see a noticeable increase in power with dyno proven gains of 18 Horsepower and 15 ft/lbs of Torque at the rear wheels.

    Aggressive Sound. AFE's Mach Force-XP Axle-Back Exhaust not only improves the power and performance of your GT, but it also improves its sound as well. Employing a pair of high flow straight-through mufflers, this Mach Force-XP Axle-Back was engineered to absorb high pitch tones while producing a rich powerful sound. This Axle-Back will delivery a loud aggressive exhaust note with minimal drone.

    Quality Construction. AFE Exhaust Systems are 100% handcrafted in the USA with pride. This AFE Axle-Back is fabricated from MIG-welded stainless steel tubing for superior strength and long lasting corrosion resistance. Featuring mandrel bent 3" diameter tubing and a set of straight through mufflers, this Axle-Back will significantly out flow the factory exhaust system. AFE's Mach Force-XP Axle-Back includes a pair of 4" 304 stainless steel double wall exhaust tips that are polished to a brilliant shine. The tips are laser etched with the AFE Power logo for aggressive good looks.

    Direct Bolt-On Installation. AFE designed their Axle-Back to be a direct bolt-on upgrade replacement for your GT Mustang's factory exhaust system. There is no cutting or extra modifications required. Installation of this AFE Mach Force-XP Exhaust can be completed in about a two hours with just basic hand tools.

    I have the stock Axle-Back on my 2011 mustang GT , Does it require a tuning after installing the AFE Axle-Back to get the 18HP ?


    • The increases of up to 18 RWHP and 15 ft/lb RWTQ were gathered with a Dyno run we would recommend grabbing a tune in order to get the most out of performance from this AFE Axle Back.

    Will these be louder than the corsa axle back? And, if I have a KN CIA and a tune, do I need to tune again after install. Thanks


    • This axle-back setup will not be as loud as the Corsa axle-back which is one of the loudest that we offer on the site. As far as tuning goes, since you are only looking at a new axle-back exhaust you will not need to retune your vehicle.

    How are these any different than Magnaflow Streets??


    • These will have a slightly different sound than the Magnaflow street item #48052 as both of these muffler chambers have no packing but Magnaflows are perforated differently than aFe's.

      Perfect mufflers

      These sound great. Startup has a nice bark to it but they quiet down pretty quick. Idle and cruising in 6th are as quiet as stock but when you get into it you for sure hear the difference.
