You will be smiling with every cold start when you upgrade your Mustang GT's exhaust to the Roush Cat-Back. This system offers a rowdy sound that takes your Mustang to a whole new level. Let people know your Mustang has a powerful 5.0L Coyote under the hood with this exhaust. 

Performance to match the sound. The Roush exhaust system reduces the restriction in the exhaust. This improves power and works well with other modifications like cold air intakes and upgraded manifolds. 

Modern system. Perfect for the S550 and its high-revving V8, the Roush exhaust provides a modern sound and is able to adapt to active exhaust systems. The dual high-flow mufflers give your Mustang a powerful and loud sound. With the active exhaust module kit installed as well, you have the ability to change your exhaust sound and volume while on the go.
