I think your muffler might work real well. We have

never tried a square

can. That might break up the sound waves with all

sorts of bouncing  around in there.

Hi Jerry;

"Just some food for thought" :)

       Going by sheer EBE, (Eye Ball Engineering) & gut
instinct.........Blasting the exhaust against a flat
surface must bounce back some pretty big pulses against
the opposite PARALLEL wall......What if, you bounce the
same pulse against four (4) walls...See attached, should
be quieter.

                                      Butch

Sounds like a great idea Butch.
