I'm a fan of small r/c motors. With expansion chambers.
There are 2 basic ways to quiet a 2 stroke.
Baffles, back pressure, and restrictions.
And
Tuned pipes.
A properly made tuned pipe has many drawbacks. It only gives more power at specific rpm's. It is big. It is heavy. But, when set up correctly, they work well. They quiet the motor, and increase power.
Baffles, back pressure, and restrictions, are the most common way to quiet a 2 stroke. They are small. They are light weight. And, they also PROTECT the rings from cold air, in the exhaust. When you drill extra holes, in a small muffler, you let pressure out faster, you (usually) make it louder, and a bit more power. For this reason, you may need to add hearing protection to your ears, if you don't want hearing aids @ 45 yrs old.
Some saws are too loud with stock muffler.
The best way to silence a saw, is to leave it at the house. And get a hand saw! But, that's not going to get a cord of wood in a few hours.
So, don't forget the hearing protection.
