Anyone out there know any different?

There are two schools of thought regarding stepped and non-stepped headers. Stahl makes a great header, and they also make stepped headers. Nevertheless, when you look around the pits at the fast cars in many classes, they are running stepped headers. From a technical standpoint, a properly designed stepped header, is the only way to go.
