I have a collection of discarded/destroyed/melted mufflers. I'm still on the lookout for the "perfect muffler". I'll let you know when I find it. So far, the only thing that works every time is the Lighspeed 33G.

At one point a few months ago I added a SuperTrapp to my existing exhaust just to see if it would tame it a little. Cost me about 500RPM on the top end with little or no improvement in the sound output.

Earnest,
I believe that the SuperTrapp muffler is an example of a band gap device and it worked well, if properly tuned.
I think the large block idea has merit too, but you will have to allow enough thickness to prevent the tubes that see the exhaust first to fight the harmonic vibration and heat. Different size diamonds in the exhaust stream might also help fight harmonics.
