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.

Square can be problematic, with their large flat sides and tightish corners.
I tried a couple on an experimental and they would not last long at all, I
think they were eight and ten hours each. They are used in auto applications
but there they do not see the heat and vibration of an a/c cowling. Of
course if you don't mind the weight and drag penalties then out in the
slipstream behind the cabin they might be okay. Isn't TC using a set up like
that ?

Guys, snap out of it :) Everybody is thinking of a shoe box welded all
around. The whole thing can be bent from one piece of stainless with round
corners and minimum welding.the sides can be slightly oval too for rigidity.

Sounds like a spintech.

I hope we are talking about tangential mufflers.
There are plenty of off the shelf cheap in line mufflers.
