In addition, OP, if you dont want the headache of dealing with all of that because it will take it months to process and clear, you could just buy a bumper which I doubt will cost you more than $500 for a painted new one if you shop around. My real worry is why the exhaust was sitting so high in the first place. It is held on by a hangar that is in a fixed position, I would check the underside of your vehicle for more damage than just the hangar. (I wouldn't be too surprised if they welded something to hold it in place which could actually make your total repair tricky which is why I suggested going to an OEM shop for a simple quote to fix this whole thing.)
