Dear Paul
      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.

Worth a try. Easier to build.

When this was discussed before, someone with experience warned the flat side
would flex from the pressure pulses and cause cracks at the corners in short
order.   Herb

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.
