      Achieve Horsepower and Torque Gains. Let your Mustang breathe better with the X-Force Varex Cat-Back Exhaust. This system facilitates unrestricted airflow from the catalytic converter to your exhaust tips resulting in speed and power gains. Unleash your Mustang on the streets and on the tracks with an X-Force Exhaust System powering up your drive.

      Unique Adjustable Engine Tone. Drive confidently down your suburban neighborhood without your neighbors complaining and then rev up your engines and fly on your roaring car while out on the open roads. The X-Force Cat-Back Exhaust enables you to do all this with the Varex mufflers’ unique adjustable exhaust sound. Switch from a quiet stock sound whenever the muffler is closed, to a loud deep race tone when you fully open the muffler valve. With the X-Force Varex Mufflers, you don’t have to compromise.

      Impressive Production and Premium Materials. The X-Force Varex Cat-Back Exhaust is built from solid 304-grade stainless steel tubes. These are mandrel bent and welded seamlessly by passionate craftsmen who are proud of their work. The major components of this system are the Varex mufflers, which are engineered to provide dual roles - a chambered stock muffler and a high-performance straight-through muffler. The surfaces are highly polished to provide not just an aesthetically pleasing exhaust, but also to ensure protection from corrosive elements.

      Modifications Are Not Needed. You actually don’t need to hire a professional mechanic to do the installation for you. All you need are a few basic tools and some spare time to read through the detailed instructions that come with this kit. To make the job easier, a complete set of mounting hardware is also included.

      X-Force’s 5-Year Warranty. X-Forces warranties the X-Force Varex Cat-Back Exhaust against factory defects for 5 years (accessories are covered for a year). This non-transferable warranty is valid only for products that are installed, used, and maintained as instructed by the manufacturer.

      Application. The X-Force Varex Cat-Back Exhaust fits 2015 to 2020 Ford Mustang EcoBoost models without the Active Valve Exhaust.
