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.

Have you got
1. a picture of this
2. a internal design layout of that muffer with dimensions?

I would like very much to make a couple for my engines, I have been
considering this issue for a while now.

Thanks in advance

There is nothing inside David. Here are a few old 2D's and 3D's.

Does anyone know anything about how Everett drilled/tapped the four bolt
holes
for his exhaust bolt pattern on the rotor housings?
Any problems? how deep?  into the water jacket?, bonded in? any special
taper? etc?
I would really like to get the exhaust as far away from the intake as
possible.

Thanks
Cary

I would not drill into the water jacket.
We have no dwgs on this configuration.
