Who Is Hedman Hedders?

Bob Hedman, the founder of Hedman Hedders, sold his sought-after exhaust tubes to fellow racers participating in the salt flats of the Mojave Desert. But what he did not realize is that, what started out as a side hustle to earn a few dollars to support his racing hobby, turned into one of the premier header manufacturers in the world.
