Maybe what
is needed for the rotary is something like this…

[FlyRotary] Re: Hushpower Muffler on Renesis.
The Renesis has a
much milder exhaust due to the side ports. I have a 13BREW- the turbo version
p-port exhausts without the exhaust splitters. This has got to make
the most agressive exhaust pulses of any of the 13 B engines. It is not
turbocharged, by the way.
If I can continue to
use the Hushpower with the guts blown out, I will. I just saw a line of
mufflers by this company that looks promising:

Renesis.
I've had a Hushpower
II Resonator on my Renesis for 250 hrs of flying and 300 total run time.
After about 230 hours I took it off and inspected it. The insides were
wrecked, burned and mostly gone. I cleaned it out and reinstalled it on
the plane. It now is just a larger exhaust pipe and the neighbors
say it is a little louder than before. I do have the Renesis
exhaust blowing into a 4 inch dia. X approx. 6 inch long swirl tank that
reverses the flow from forward to rearward.
I never experienced
any loss of power as the inner parts of the muffler were
failing.
