Helpful tip: If the exhaust tips hit the body the easy fix is to duct tape a small scrap piece of sheet metal to the upper side of the exhaust tip to protect it … use a radius file allow it follow the shape of the tip as you file a gap between the exhaust and the fiberglass. You'll end up with a 1/4" - 5/16" barely noticeable radius above the exhaust tips. Be sure to seal the raw edge of the fiberglass with paint.
