Stop choking your Shelby GT500 with a stock factory exhaust system and enjoy more horsepower with a Magnaflow Competition Axleback. By reducing back pressure and giving your Mustang GT500 a free-flowing exhaust, you'll see great power and torque gains.
Aggressive Muscle Car Sound. The Magnaflow Competition Axleback has a straight through muffler delete design for minimal restriction and the most aggressive sound you can get with the stock factory cats still in place all while improving exhaust flow for more power.
Magnaflow Quality. Constructed from 100% stainless steel for long life and durability, this Magnaflow Competition axleback exhaust system features free-flowing mandrel bent 3" tubing and two quad 4" black finished tips that exit in the stock locations for impressive styling.
Made to be a direct bolt on, this Magnaflow axleback will bolt straight up to the factory piping without any extra modifications required on your the 2013-2014 Shelby GT500 to give it the deepest, most aggressive sound possible.
