I have a set of fenderwells made by tubular parts automotive. These route only three of the tubes through the fender and one under the chassis and then out to the collector outboard of the frame channels. With only three tubes in the fenderwell tire clearance is greatly improved. I am not sure if they are still made or not. Company was in NJ. I sold my hooker 2" supercomps because of tire clearance. They never even made it on the car. I was going to use 13/4" b body headers and modify the drivers side to fit but found the tubular parts automotive ones used.
