If you are looking for the iconic ROUSH sound, as well as superb styling to the rear end of your 2011-2012 Mustang, you have come to the right place!

This Mustang Exhaust w/Square Tips is designed for 2011-2012 5.0L V8 Mustang. The square tips only fit, and require, the ROUSH 2010-2012 Mustang Rear Valance.

The muffler in this system differs substantially from the conventional fiberglass-packing found in other mufflers. The ROUSH muffler produces a less inhibited sound, increased air flow (maximizing power), and increased longevity (with no fiberglass that would break-down over time). Another great feature of this exhaust kit is the lack of the typical “in-cockpit boom” at cruising speeds found with most performance exhaust systems.

The chrome flashing used in the manufacturing process for the 304 Stainless Steel exhaust tips is bonded micro-porously to the metal surface. The result is a finish that is highly resistant to cracking from localized damage and heat color change. Conventional chrome plating is susceptible to cracking and flaking, especially when subjected to heat (as is found with an exhaust). The inlet pipe and mufflers are made from 409 stainless steel for enhanced durability.

Not only is the sound high-quality with the ROUSH 2011-2012 Mustang Exhaust Kit, but the looks are as well! Installation of this exhaust is quick and easy. The exhaust uses the factory hanger mounting positions (you won't have to fabricate your own). This kit also features new OE-quality spherical clamps for a great fit.

This kit carries ROUSH’s 3 Year/36,000 Mile Limited Parts Warranty, and has no effect on vehicle emissions.

roush exhaust and valance

Rating of 5 out of 5 stars 5 / 5

I had this exhaust and valance installed at the nearest Roush dealer. I get compliments on the sound and look of the system all the time, and it sounds great to my ear. As quiet as stock at turnpike and highway speeds, but comes to life in an instant when accelerating. This system has the ideal sound for the 5.0.
