American Racing Headers is a great example of what culminates when highly skilled fabricators, with a complete understanding of motorsports and the science behind the parts they create, come together to take on a new world of high performance.

Taking the Bull by the Horns approach, American Racing Headers was formed to prove that superior quality and outstanding performance can and will be the keys to success.

In 2005 Ford changed the future of muscle cars by bringing back the classic look of the 1960's mustang.
