2011-2014 Roush Mustang GT 5.0 Axle-Back Exhaust Kit 421127
Distinct aggressive sound. Uses 409 stainless steel in the construction of the pipes and muffler. Roush exclusive open-chambered design that will not deteriorate over time unlike conventional fiberglass roving material. Exhaust tips are made from 304 stainless steel and finished with a unique chrome flashing process. Chrome-flashing on tips provides heat resistance to color change. No negative impact on any type of emission devices. Hollow chamber yields higher airflow. Highly tuned system avoids the annoying in-cockpit boom, which can occur with competitive systems. Fits both Ford factory and Roush rear valance. Tips have oval-shaped openings: 4" x 4.5". Installation is quick, easy, and uses all factory hanger locations and pierce points. No modifications to the vehicle are necessary. All the hangers are chromed for superior appearance and corrosion resistance. New, high quality OE-spherical clamps are included in the kit.
