      Description

      Aggressive Raspy Sound. Let everyone know your 2015-2017 Premium Package GT has arrived with the aggressive, raspy sound of this Roush Quad Tip Passive Axle-Back Exhaust. This innovative Roush Exhaust system features a hollow, open 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 fully mandrel-bent 304 stainless steel for a durability, corrosion resistance and long life, the Roush Axle-Back Exhaust features two unique open chambered mufflers with 304 stainless steel dual wall quad tips. The 4" quad tips are finished with a new chrome flashing process that is resistant to discoloration due to exhaust heat.

      Passive System. Featuring block off plates for the two inner exhaust tips, this Roush Quad Tip Passive Axle-Back gives you the ability to cruise with just the two outer tips open or all four tips. Simply remove the inner plates to further improve the sound and performance of this Quad Tip Exhaust.

      Active Ready Kit. This passive exhaust system is also designed as an "Active Ready" Kit, which will allow you the option to easily remove the included block off plates and simply bolt-on Roush's Active Exhaust Module (sold separately).

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

      Application. This Roush Quad Tip Passive Axle-Back Exhaust System is designed to fit fastback or convertible 2015-2017 GT Mustangs equipped with the Premium Package and the required 2015-2017 Roush Rear Valance installed (valance sold separately).
