The OEM S550 Headers on the 2015+ 5.0L Mustang GT leave a lot to be desired. The stock unit is manufactured with the goal of suppressing the motors sound as much as possible. This sound deadening robs the motor of vital flow and horsepower. Take your horsepower back with the LTH Long Tube Headers!

The LTH S550 Headers are finished in our exclusive Titan™ finish that provides an all over matte finish and added durability.
