I'd whip it off and see if it can be repaired. 4 x 13mm bolts at the headers.....I use a 1/8th ratchet with long bars as it fits past the pipes and straight on to the bolts...easy. then 2 x 13mm bolts under the gearbox, a tap on the bracket and it should separate, then drop it off the rubber hangars. as it's in 1 piece it'll be heavy and awkward but no more than an hours work.

Now I am having to replace both boxes. Checked the service history as well and it seems that the exhaust was replaced in 2001 by a MB dealer.
