If that pipe is good enough to work with a little, I've seen muffler guys torch and bend the pipe somewhat. But there has to be some way to get leverage. I think any decent local exhaust shop could probably chop out a small section of pipe and bend another for not too much $, just enough to get the clearance you need. Tailpipes cost $80 a side where I go, but if you just had two little bends installed I'm thinking fifty bucks or so.
