Aggressive Raspy Sound. Designed for 2018-2023 GT Mustangs that are not equipped with the factory Active Exhaust, this Roush Axle-Back Exhaust will let everyone know you have arrived with its aggressive raspy sound. This innovative new 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. Roush manufactures their exhaust systems from mandrel-bent 304 stainless steel for durability and corrosion resistance. This Axle-Back Exhaust features two unique open chambered mufflers that improve exhaust flow. The system includes two dual wall 4 inch quad tips that are finished in a new chrome flashing process that is resistant to exhaust heat discoloration.
Cut & Clamp Installation. The installation of this Roush Axle-Back Exhaust will require 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 2018-2023 GT Mustangs that are not equipped with active exhaust from the factory.
