The Ford Racing axle-back muffler system for 2013–2014 Mustang GT includes two T-409 aluminized steel mufflers with dual polished 4" tips and a GT500-style rear lower valance. It produces a throatier exhaust note and is designed to change sound and character compared with the factory setup. The kit includes installation hardware; cutting the original lower fascia is required for fitment and the system is clamp-on for installation.
