Tony Bingelis's book, "Firewall Forward" has a section on "Swiss"
   mufflers. The muffler consists of a tube rolled out of SS mesh
   surrounded by glass mesh (SS mesh would be better for our application,
   glass would not last) inside of a section metal tubing about 3-4 inches
   in diameter. The longer the muffler, the quieter I guess it would be. I
   don't think anyone has tried this on a rotary engine.

   Yes they have and it burned out shortly as I recall :)

I've got a Moroso Hushpower muffler on my engine. I'd like to get the
plane a bit quieter, I wonder  if I could put a swiss muffler on
downstream of the regular muffler. Instead of using glass packing, I
wonder if SS wool would last.
