exhaust replace or not?

[AlpineMsix]

So i was rear ended 2weeks ago, not that hard, but enough to bend my exhaust tips and scratch my oval tip(4.8) so the body shop, re polished and refinished my oval tips. But i still notice that one of the exhausts is pushed in and is a bit out of shape more then the other..

So i took it to a muffler shop thinkin they could simply adjust it;
they said they could not due to the actual exhaust tips that go into the oval piece are bent, so they said the only thing i can do to make it look normal again is to get a new muffler piece.

Im not tryin to go out and spend 600 on new muffler canister simply because my exhaust tips are out of alignment

what do u guys think??Suggestions?
