Free Flowing Exhaust. Magnaflow delivers the ultimate free flowing exhaust for the 2005-2009 GT, Bullitt, and 2007-2009 GT500 Mustangs by eliminating power robbing restrictions to put more horsepower and torque where it belongs - at the rear wheels.
Aggressive Muscle Car Sound. The Magnaflow Catback Exhaust System features a set of straight through bullet-style "MagnaPack" mufflers to give your Mustang the loud aggressive exhaust note of the muscle cars of yesteryear.
Quality Magnaflow Construction. Each piece of the Magnapack catback system is constructed from mandrel bent 2.5" stainless steel tubing for long life and a perfect fit. The system features two Magnapack straight-through mufflers that end with brightly polished 4" stainless tips, that exit in the stock location for impressive good looks.
Application. Made as a direct bolt on, this Maganflow 'Magnapack' catback will bolt straight up to the factory Mid-Pipe without any modifications required on the 2005 to 2009 GT, Bullitt, and 2007 to 2009 Shelby GT500 Mustangs to give it a deep aggressive sound.
