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!

I don't recall hearing about a tangential muffler
unless it is the one with the cooling air through it
and the rectangular exhaust pipe. The article I just
read mentioned having only two pipes in it instead of
three.

The RX8 engine or Renesis has four exhaust ports.
The two center ones being very close together so it
looks like three pipes.
