Magnaflow's Cat-Back exhaust system has been dyno-tested to add horsepower and torque onto your 2005 to 2009 GT Mustang while giving it back much of that Muscle Car Roar present in the early days of Mustang design.
The Magnaflow system is 100% stainless steel and utilizes 2.5" mandrel-bent pipes with 4" polished tips. Each kit comes with a pair of Magnaflow's chambered mufflers that are purpose-designed to deliver huge sound in a compact package.
This cat-back system is a direct bolt-on replacement for the OEM system and uses the OEM mountings and piping. Each kit includes installation hardware for a quick, easy slip-on fitting.
