I guess you could get the diffuser off with the bumper still on. You can see most of the clips around the diffuser if you just poke your head underneath. The clips that hold it on are very weak and prone to breaking. Be careful. The ones along the top edge will be the hardest to get out without damage.

could it be done if the muffler and pipes were removed first?
