Still using it on the 20B, think the sound level has increased slightly, maybe because the packing in the resonator portion in front part has gone away. Still using the Hushpower II on the Renesis. The Renesis is quieter than the earlier 13/20B with all else being equal.
Recently put a new exhaust system on my car (stock was completely silent, hated it) and like the sound so much I'd put it on my plane if it fit and didn't weigh too much.

Hey Tracy,
Any updates on the Aeroturbine Muffler? Have you tried one on the
Renesis yet?
Next time you head west, please stop in to see us so I can hear it
in operation. :-)
Thanks,
Charlie

Re: Aero Turbine Muffler test
Two flight tests totaling 3.5 hours so far on the Aero
Turbine muffler (XL version with resonator built in) on
the 20B powered RV-8. Best muffler tested so far.
Quieter than even the Spintech which was the previous
best. The irritating high frequencies are virtually
eliminated from the exhaust. No noticeable increase in
drag. No increase in power or fuel economy either in
spite of claims printed on the box. The beautiful
polished 304 stainless finish disappears pretty quick with
the rotaries hot exhaust. If the muffling performance
holds up I'll be very satisfied. At $79.00 it's a
bargain.
