A new Mustang for 2015 means there needs to be new options from Roush as well, options which are sometimes even more eagerly anticipated than the car itself. Among the first will be this axle-back exhaust. Systems like these don't do much for performance, but they do make a pleasing sound when they're done right, and Roush can always be counted on to do things right. So we've got a video of the new system making some lovely sounds.

As always, kits like these will also be offered as part of a number of packages from Roush, ranging from appearance packages to full-on race options.
