      Video Review & Installation

      Hey everyone I’m Justin with AmericanMuscle.com and I’m checking out this Roush axle-back exhaust system for all 2011 and up GT Mustangs. This unique axle-back design from Roush features an open chambered muffler, which allows for a more aggressive exhaust note, while keeping drone to a minimum. The system is constructed from 100% stainless steel and features two chambered mufflers and two four inch stainless steel polished tips, both inscribed with the Roush logo. Simple bolt on installation should take you no more than an hour. Let’s hear how this axle-back compares to the stock exhaust.

      Description

      Aggressive Muscle Car Sound. Let your engine howl with a Roush Axle-Back Exhaust. This innovative new Roush exhaust system features a hollow chamber muffler that results in increased air flow, and a unique sound, with no in-cabin "boom" normally found with performance exhaust at cruising speeds.

      Quality Roush Construction. Constructed from 409 stainless steel for a durable long life, the Roush axle-back exhaust system features two unique chambered mufflers with 304 stainless steel 4" tips. The 4" tips are finished with a new chrome flashing process that is resistant to discoloration due to exhaust heat.

      Application. This Roush Performance Axle-Back exhaust system will fit the 2011-2014 GT & 2011-2012 GT500 Mustangs with either the factory GT rear valance or the Roush rear valance.
