      Description

      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 2020 Mustang GT350s.

      Live in Missouri. Will car pass emission test?

      I have a 2016 mustang Gt with the Shelby Gt350 rear diffuser/valence. Will this exhaust work on my GT ? If it requires slight modifications that’s fine but can it be Done ?

      • Unfortunately, even with the GT350 rear valance installed the Corsa Xtreme 3 in. Cat-Back Exhaust is only designed for GT350 and GT350R, we would suggest something like this here:https://www.americanmuscle.com/frpp-touring-catback-gt350-valance-1516gt.html
