Modifying the exhaust is a great way to improve your sound and performance. Here’s what you should know about cat-back and axle-back exhausts.

There's no doubt that the factory exhaust that comes on the 2015-2017 Mustang GT is quiet, restrictive and overall boring.

Find out how to install it in this guide!

As a cost-effective way to get a great exhaust note out of your EcoBoost Mustang, an axle-back system makes an excellent upgrade. Check out our comparison between the Roush and Accelatec axle-back options.
