Roush's Mustang V6/EcoBoost Axle-Back Exhaust is sure to give your S550 a nasty sound. The high-flow mufflers increase the volume and give the exhaust a more aggressive tone. 

More noticeable idle. You will notice a deeper and louder idle after installing this exhaust. This will make your Mustang stand out more at lights and when stopped. 

Throaty acceleration. The design of the mufflers really opens up the exhaust. The system provides a throaty and mean acceleration that will make driving more exciting. 

Excellent upgrade. Roush's axle-back requires no welding and uses the OE mounting points. It is made from T304 stainless steel for a lifetime of performance, supported by the Roush Limited Lifetime Warranty. It is compatible with the factory exhaust valance for a clean appearance.
