If I remember right it was said that a sq. tail pipe deadened the
exhaust noise.What if we made the muffler sq also so the sound would
bounce around and be deadened. Give me some feed back on this subject.

Ed: I have designed (in the windmills of my mind) a square muffler,
spiraling interior baffling, to sit under heat baffling' insulating sheet
under a little deeper, welded up aluminum oil pan' all sitting on motor
mount, since it is for amphibian pusher where engine can sit a little higher
than rvs, etc..  If someobdy like PL doesn't draw us up one, I will have to
actually commit it to paper and/or just weld it up and go from there with
photos, one of these days.
