The S197 Mustang GT has an amazing sound, thanks to it’s 5.0L. 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 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 S197 Mustang Headers. Truly any S197 Mustang GT can benefit from a set of proper headers. Free up your horsepower and let that V8 sing!
