need help
i put my new hedman long tubes in only to find out that on both sides they have clearence problems. on the drivers side they contact the motor cross member/strut tower area. and on the passenger side they contact my fuel lines. i was wondering if any one else has had these problems and how they fixed them. i dont want to dent my headers if i can help it.

How old are your motor mounts? If they are original, they could be really worn out, letting the engine sag down alot. Fresh ones might jack up the engine enough to solve your problem.

They can, i've heard of them sagging an inch or more. You gotta remember here, that they are supporting a 600lb block of metal, so it pushes down pretty hard on them.
