The GT350 Mustang has an amazing sound, thanks to it’s Voodoo 5.2L. Both the Gen 2 and Gen 3 Coyote sound amazing with headers. Also headers are one of the best mods on this platform, as it gives you more power. Combine this with the incredible sound and you have a winner. Accordingly modifying the catback section of the exhaust will give you more sound, but the headers are really where the power is at.

Certainly the Gen 2 Coyote Headers free up a lot of power, especially when the car has a tune for the added airflow. Consequently the same is true for the Gen 3 Coyote Headers. Truly any GT350 Mustang GT can benefit from a set of proper headers. Free up your horsepower and let that Coyote sing!
