I have a set of SuperComp Heddman Headers on my 350 in my 84 Caballero. They run the third or fourth tube back around the outside of the frame and the other 3 on the inside. I'm having trouble with my tires hitting the header tube when in a full turn. Just didn't know if anyone else had experienced this. I was thinking about putting some longer steering stops in because I really don't want to go with smaller tires beacuse of the lack of handling.
