      Description

      Aggressive Muscle Car Sound. Let your 5.0L Coyote engine howl with a Roush Axle-Back Exhaust. This innovative new Roush exhaust system features a hollow chambered 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 mandrel bent 304 stainless steel for a durable long life, the Roush axle-back exhaust system features two unique open chambered mufflers with 304 stainless steel 4" tips. The 4" tips are finished with a brand new chrome flashing process that is resistant to discoloration due to exhaust heat.

      Cut & Clamp Installation. The installation of this Roush Axle-Back Exhaust requires cutting and removing the factory muffler assemblies and clamping the new muffler assemblies in place. Clamps and instructions are provided.

      Application. This Roush Performance Axle-Back Exhaust System is designed to fit the all 2015-2017 GT Mustangs, including Fastback and Convertible models, for both great looks and great sound.
