Uncompromised Sound & Performance for Your 2015–2017 Mustang GT
Take your S550 to the next level with the Corsa Xtreme Cat-Back Exhaust System, designed specifically for the 2015–2017 Mustang GT Fastback. Known as Corsa’s loudest and most aggressive exhaust series, the Xtreme delivers a raw, race-ready sound that turns heads without the annoying interior drone—thanks to their patented Reflective Sound Cancellation® (RSC®) technology.
This system is built for performance and longevity, featuring TIG-welded 304 stainless steel, mandrel-bent 3-inch tubing, and your choice of quad 4.5” polished or black tips. With a straight-through muffler design, you'll experience improved throttle response and increased horsepower, all while giving your Mustang that true American muscle car tone.
