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

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:

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.
