This 2010 Mustang Exhaust System improves the power, fuel efficiency, and sound of your Mustang.

This high performance system generates a loud and throaty-sound.

The mandrel bending process used for the tubes of this system maintains a consistent inside diameter through the bended area. This method allows for a significant increase in flow over stock/serrated-bent pipes

Due to this increased efficiency, both latent power and fuel efficiency are realized.

This Mustang exhaust kit is made of T-304 stainless steel, providing for resistance to corrosion and staining. This exhaust system features exhaust tips, mufflers, and required hardware for installation.

**ROUSH Performance recommends checking your local noise ordinance levels prior to purchase.
