Wrapping muffler to reduce resonance

I own the first Deluboz (Che) muffler from three or four years ago... sounds glorious with the top down or at the track... as long as you don't hang out in the 2-3k rpm range. I'd just avoid that range altogether, but it's quite a bit of extra work, requires staying in a lower gear most of the time around town, and it's really starting to annoy me.

Someone on the board suggested using header wrap to wrap my twin muffler chambers in an effort to reduce cabin resonance. Before I haul off and buy the stuff to do this mod, I'd like to know what other board members think or have tried.

What causes resonance? Will wrapping a muffler chamber with something fireproof and dense cut down on the resonance?
