Interesting question. I would think the least back pressure caused by the outlet of the muffler would be best. Assuming that all the tuning and scavenging by the exhaust system had taken place before the muffler. Usually the muffler will result in some restriction itself.

Now it sounds like you want some back pressure? Why?

The thing is, you want the exhaust, including the muffler, to work in concert with the rest of the motor. So the muffler outlet size is only one piece of the puzzle.
