FLOWMASTER American Thunder/Classic Axle-Back Kit
Ford 2005-10 Mustang GT / Shelby GT500

in stock 2005-10 Ford Mustang American Thunder® Classic System

Flowmaster announces the release of their new Axle-back kit for the Ford 2005-10 Mustang GT / Shelby GT500. Since the early 1980’s when Ford released the now famous 5.0L HO engine, Flowmaster- Equipped Mustangs have become the signature sound of the modern muscle car era. Flowmaster’s new axle-back system for the latest generation of 2005-10 Mustang’s delivers improved performance, looks and a sound reminiscent of those early 5.0L cars.

Featuring Classic square cased 40 Series® mufflers, the kit follows the factory exhaust routing, utilizes the factory hanger mounting points and includes all necessary mounting hardware for an easy and perfect fitment. Designed for the serious enthusiast who really wants to hear their pony breathe, these mufflers produce a deep and aggressive exterior tone on the throttle, along with a considerable amount of interior sound.

For those looking for performance, but with a tamer sound, Flowmaster also offers a quieter alternative (listed below).

FYI: *Sometime during the mid-production run on 2007 Mustangs, Ford realized that they were loosing money on the intricate metal/rubber exhaust hanger they designed for the 2005+ Mustangs. Thus they switched over to a cheaper rubber only hanger system to attach the factory exhaust. Unfortunately, this system will ONLY work with factory exhaust and will not allow for installation of aftermarket exhaust. Switching to the 2005 to mid-2007 style hangers solves this problem and will allow for installation of any 2005+ Exhaust System on late production 2007+.
