Is my exhaust FUBAR?
fuBAR as in "Beyond All Repair" in this case?
If you have an A4, with the car on a frame hoist (NOT sitting on the wheels), you might try brake torquing to see if it hits, and where.
From your desription, if it hits, you MIGHT be able to bend it slightly, maybe carefully heating the pipe in certain areas. If not, cuting and refitting sounds like the plan. If the original installer doesn't want to make it right, go elsewhere; you don't want to be in a pi$$ing contest with a guy working on your pipes!
Try a racecar fabricator if there's one in your area.
Good luck!
