      More Power and Better Performance. This AFE 3" Cat-Back Exhaust eliminates the narrow 2.25" factory piping and bulky mid pipe resonator with 3" mandrel-bent tubing and a smooth flowing Y-pipe for unrestricted exhaust flow. Together with a pair of straight-through mufflers this Mach Force-XP Cat-Back will significantly improve the flow of your EcoBoost Mustang's exhaust, when compared to the stock cat-back system, for more power and better performance. Dyno proven power gains of 16 Horsepower and 17 ft/lbs of Torque have been seen at the rear wheels.

      Aggressive Sound. AFE's Mach Force-XP Cat-Back Exhaust not only improves the power and performance of your EcoBoost, but it also improves its sound as well. Featuring a pair of high flow straight-through mufflers for an aggressive tone, AFE utilizes a Y-Pipe to balance exhaust pulses which minimizes drone while adding a nice growl. Together this setup will add an loud aggressive sound to your EcoBoost's exhaust with a little extra growl 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 bright mirror like finish. The tips are laser etched with the AFE Power logo for aggressive good looks.

      2.25" to 3" Adaptors Included. This AFE Mach Force-XP 3" Cat-Back can be installed with an AFE 3" Down Pipe, as well as the factory 2.25" Down Pipe with the use of the included 2.25" to 3" step-up adapter. This adapter allows you to conveniently upgrade your EcoBoost Mustang over time as your budget allows.

      Direct Bolt-On Installation. AFE designed their Cat-Back to be a direct bolt-on upgrade replacement for your 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 2015-2021 Fastback EcoBoost Mustangs equipped with the turbocharged 2.3L 4-cylinder Engine. Does not fit convertible models.

      Please Note. This Cat-Back Exhaust System is intended for use on EcoBoost Mustangs with the factory 2.25" down pipe or an AFE 3" Down Pipe Kit installed.
