Driveshaft slightly contacting muffler - solution?

There's an H pipe a few feet upstream of the mufflers which sit under the rear seats, then theres hangers just aft of the rear axle. The H-pipe holds it in place pretty tight, I can't move it by pushing on it. I think the H-pipe would have to be cut and widened slightly.

Problem is, I've busted my tail to make a 'cruise night' tonight so it sucks that this would keep me from it. I think I'm gonna try to grind a little off of the weld on the muffler.
