AGGRESSIVE, RASPY SOUND
Let everyone know your EcoBoost Mustang has arrived with the aggressive, raspy sound of this high-performance Quad Tip Roush Axle-Back. 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
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.
