Has anyone tried a single tip GT exhaust on there car? When I got my car it had a four tip GT exhaust on it. This caused a problems in that the tips would hit the rear apron. The other thing was the heads have been shaved on these cars so the exhaust pipes need to shrink inward by about 1/4 inch. Also the single tip may need to be lenghted to lineup with the cut out in our rear apron.
