    Aggressive Sound, Better Design. This Roush Axle-Back Exhaust with Black Tips, which is exclusively designed for AmericanMuscle, will make your Ford Mustang’s exhaust sound better. It offers an aggressive sound for everyone to hear without any in-cockpit boom or drone. This drone noise is fairly common with other performance exhausts, but since drone is virtually eliminated with this system, you get to enjoy comfortable driving, no matter the cruising speeds.

    Increase Power and Performance. Featuring an open-chambered muffler design and mandrel-bent tubes, this assembly offers unique maximum airflow that increases horsepower and acceleration. Enjoy faster speeds and a better throttle response with this upgrade.

    Superior Quality. This axle-back exhaust not only sounds great, but also looks better than most OEM units out there. The included black round tips are engineered using 304 stainless steel and painted black. This process makes the tips impervious to cracking as well as resistant to heat color change. Meanwhile, the mufflers and inlet pipe are manufactured using 409 stainless steel for guaranteed quality and durability.

    Straightforward Installation. This exhaust assembly is designed to mount to existing factory mounting points for easy and straightforward installation. It comes equipped with all the necessary hardware and instructions. The installation process is intermediate level and can be done within an hour or less.

    With 3-Year Limited Warranty. This Roush exhaust comes with a 3-year limited warranty. It includes coverage for defects in materials and workmanship only. Roush will inspect and determine if the exhaust is eligible for warranty coverage.

    Application. This Roush Axle-Back Exhaust with Black Tips is specifically designed to fit all 2011-2014 Ford Mustang GT and 2011-2012 GT500 models.

    Referring to the little "loudness" scale, why does this show louder than the Roush Axleback with the chrome tips?

    • This axle-back exhaust and the Roush with the chrome tips will essentially have the same aggressive exhaust tone.
