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.

The tips are finished with a new chrome flashing process that is resistant to discoloration due to exhaust heat.
