Correct, I installed the hanger bolt and slipped the nut on a couple of turns. BTW, if it's only a millimeter or 2 just loosen up the CAT/header side and slip it back on the exhaust/CAT end and re-tighten. If you don't want to do that if you have a DREMEL ream out the hole on the flange for the hanger bolt to move forward the mil. or 2 you need.
