You run into this from time to time. Have an engine and broke, lost, or never had a muffler. Doesn't brand X fit brand Y? Does anybody have this information. Sometimes you can get and idea by going to the Macs and other mufflers sites but that doesn't always help, sometimes they just list the most common brand the muffler fits, they may not tell you that it also fits several others. This would be very useful info to put up on this or another site.
