Hi Ed, 
 
Yes, I remember your muffler experiment.   Let me ask you, is that something you had seen before?     Issues with my concept was weight, manufacturability, and it being a heat sink.   But in the last few minutes I did what I often do.  I came up with another iteration which deals nicely with those and is so simple that anybody with welding gear could make one in their shop.   It just looks a little funny.

I am in complete agreement with you.  I am currently flying with a muffler design that is:
 
1.  Designed to break up the sonic/transonic shock wave that is so shattering to the ears
2. Minimize impediment to the lower velocity gas flow.
