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:

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.
