Mike, how about exploring aftermufflers?

They can be made out of nearly anything....use your imagination. I've seen 'em made from fiberglass stuffed drink cans to silicone bulbs with holes all around them.

I'd run a tank of 16/1 then go to 20/1 for a few tanks then go to at least 24/1. Personally, I run 30/1 in the older bushed engine, 32/1 in the bearing engines.
