Dear Paul
  OK there is talk about the flat sides flexing I can go along with that
idea but now what if the sides where bent in eight equal sections to form
the circle that would cut down on big flat surfaces and would keep it from
flexing due to the small area. Any one have any ideas on that system.

Ed even a single folded flat side should be enough to break up the shock
wave
I don't think it needs to be square or eight sided.

Paul I'm including the muffler layout I did for Jerry. Don't remember if
I posted it to the list recently or not. Your memory goes first after all!
Don't remember the rest.
