More Power and Better Performance. Are you looking to add even more power to the rear wheels of your already powerful GT Mustang? Of course you are, that's why you should consider upgrading to AFE's Mach Force-XP 3" Cat-Back Exhaust System. By replacing the restrictive factory piping and stock mufflers with much larger 3" diameter mandrel-bent tubing and a pair of high flow straight-through mufflers, this AFE Cat-Back will significantly improve your V8 Mustang's exhaust flow for more power and better performance. After installing a Mach Force-XP 3" Cat-Back Exhaust System on your 2011-2014 GT Mustang you will see a noticeable improvement in power with dyno proven gains of 23 Horsepower and 19 ft/lbs of Torque at the rear wheels.

Aggressive Sound with a Rumble. AFE's Mach Force-XP Cat-Back Exhaust not only improves the power and performance of your GT, but it also improves its sound as well. Featuring a pair of high flow straight-through mufflers for an aggressive tone, AFE utilizes an H-Pipe to balance exhaust pulses which minimizes drone while adding a classic muscle car rumble. This setup will add an loud aggressive sound to your GT's exhaust with a little extra rumble that will let everyone know what you're packing under your hood.

Quality Construction. AFE Exhaust Systems are 100% handcrafted in the USA with pride. This AFE Cat-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 Cat-Back will significantly out flow the factory exhaust system. AFE's Mach Force-XP Cat-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 Cat-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.

Application. This AFE Mach Force-XP 3" Cat-Back Exhaust System with Polished Tips is specifically designed to fit 2011-2014 GT Mustangs equipped with the Coyote 5.0L DOHC V8 Engine.

If I already have an x-pipe, can I opt to not use the H-pipe on this setup?

  • It is highly recommended to use the mid-pipe included in this kit as that will guarantee proper fitment. Unfortunately without knowing which x-pipe you currently have, we would be unable to guarantee fitment with this exhaust kit.

    I can't say enough about the aFe Cat-Back system with the polished tips. AMAZING!!!!!!!!!! One of a kind exhaust note, DEEP RICH and not as loud as I thought it would be. You definitely know there is nothing stock about it. Did the install in my friends garage on jack stands. It really took longer to get everything together and set up then it took to do the install. I had to cut out the old exhaust to get it out from the axle just because of the room. We had the old exhaust out and new in about 3 hours total, to include getting everything lined up, adjusted and tightened. I would definitely recommend this products hands down.
