    Aggressive Sound. With Corsa's Xtreme 3in. Cat-Back Exhaust system your Mustang GT will have an aggressive throaty growl upon acceleration that will make people turn around and notice. While idling, the sound will turn to a deep growl. But don't worry about the noise because this system prevents any annoying droning from disturbing you inside your car. This is all thanks to Corsa's Reflective Cancellation Technology (RSC).

    Bark and Bite. This Corsa exhaust system is not all bark and no bite. Thanks to improved exhaust flow, your pony will have increased horsepower and torque. You might even see an improvement in gas mileage.

    Made to Last. Corsa builds their Xtreme 3-inch Cat-Back Exhaust Systems with 3-inch diameter 304 stainless steel tubing that is Mandrel-bent for improved exhaust flow and better-spent gas handling. The double helix X-pipe and two straight-through mufflers are built for the long haul. 4.5-inch polished, slash cut tips will add to the aggressive look of your GT.

    Bolt-On Installation. This Xtreme Cat-Back exhaust system is a direct replacement for stock exhaust systems. It bolts directly to factory mounts and requires no cutting or special tools for installation.

    Application. The Corsa Xtreme 3-inch Cat-Back Exhaust System has been engineered to fit 2015 to 2018 Mustang GT350s.

    I recently bought this exhaust for a gt and was wondering if I would have to buy the whole set up again. I now have a gt350 and would like to transfer the exhaust from my gt. Do I need different adapters?


    • Since the Corsa Xtreme 3 in. Cat-Back Exhaust is specifically designed for the 15-18 GT350, you will need to purchase the entire exhaust again in order to have a proper install.

    Does this exhaust retain the use of the factory motors for the multi-mode exhaust?


    • This Corsa Xtreme 3 in. Cat-Back Exhaust will not utilize the multi-mode exhaust, so the motors would have to be removed. The Magnaflow Competition Series Cat-Back Exhaust, item 390660 and the Ford Performance by Borla Sport Active Cat-Back Exhaust, item 394115 will still reuse the multi-mode motors.

    If I installed the gt350 rear valence on a 2016 premium gt would this exhaust fit?


    • unfortunately no the Corsa Xtreme 3 in. Cat-Back Exhaust is only designed for GT350 and GT350R, I would recommend something like this-
