I put 1 inch pipe in the one I modded, it's pretty close to that size.
If you stick the pipe 1 1/2 to 2 inches into the muffler it's not too loud. If the pipe is really short it will be quite loud.

12ga is ~ 0.70".
Why waste a shotgun barrel?

It's a barrel STUB. The choke was already cut off around 24" and I cut it further to 20" with extended mag. I don't cut up shotguns for chainsaw mufflers.
Just use a choke unless you want a sawed off shotgun.
Oops saw your post, was couple minutes to late.

Just don't go <18" or BATF/THE FIB will do a Randy Weaver on you.

Its about backpressure and flow. The diameter should be fine just make sure its long enough (1-1/2 or 2") so that it muffles the noise a bit.

Can't a guy go to jail for having a cut off shot gun? Well, maybe not if its sticking out of a muffler, but ya never know....
The 70-75 cc saws seem to run good with a 3/4 - 1 " opening in the muffler. I try to point the exhaust so that it does not melt or burn the chainsaw parts but definitely try to not point it straight forward. Some of pipe sticking back into the muffler can does help with noise reduction , will disrupt flow and cause a bit of back pressure but not enough concern unless its a full out race comparison.
