E420 Cracked Exhaust Flange
 

Does anyone have any novel ways of dealing with a cracked exhaust flange on the side of the central muffler (see picture), between the front exhaust pipe and central exhaust pipe? It looks like the cracked flange and central muffler come as one unit, so you can't just buy the new flange and replace it. I am getting an exhaust leak from this area. I could dremel the old flange off, but I'm not sure what I could replace it with. Thanks in advance.
