Hello Paul

I fired up the Renesis with the prop. on yesterday and was amazed  at how
quiet it was. That spin [tangential] muffler design is a real  winner, even though
mine has only two pipes going in at a tangent with the third going  in at
the end, it still works.
The flanges shown in the picture were too narrow to fit the Mazda
gasket. Words were spoken!

Not to be confused with the Spintech muffler.

Some of that was due to the side exhaust ports and rectangular
tubes I am sure. The Russians discovered that rectangular
tubes were effective in quieting a rotary.

Paul Lamar ...No rotor no motor.

The rectangle exhaust pipes could be very useful when fitting the
muffler into a tight space,  I will be interested to hear  about the
effect on performance.   Jerry
