This Ford Mustang Muffler, Off- Road Kit w/o Tips, will breed a loud, throaty-sound out of your 2005-2009 Mustang. These Off-Road Mufflers will improve the power, fuel efficiency, and sound.

The exhaust kit is made of T-304 stainless steel, providing for resistance to corrosion and staining.

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 axle-back exhaust system bolts on and requires no cutting and attaches to the factory midpipes.

As opposed to the complete ROUSH Mustang Off-Road Exhaust System (part #401339-discontinued), this package does not include exhaust tips. This package allows you to upgrade from the "legal" version of this system (part #401338) to the "off-road" system. If you are looking to get the great sound of a ROUSH exhaust system on your 2005-2010 Mustang GT without changing your rear fascia, you can do so with the ROUSH Extreme Exhaust system (Part #421915).
