For sale: Roush axle backs for 2011-2014 Mustangs. I had these on my 2014 GT for about five years, approximately 60k miles. As you can see from the pics, they could use a little bit of polishing but I haven’t had any issues as far as leaks and they sound great. Getting rid of them because I want to go with something a slightly quieter. Asking $300. Located in Northern Virginia but willing to discuss shipping.
