Rear Exhaust Engine/Muffler Length

I need to know the overall length from the front of the drive washer to the center of the exhaust outlet of a typical rear exhaust with muffler (not pipe) set up for a 60 - 65 size engine. Understandably this will vary somewhat depending on the manufacturer. I suspect the Stalker may be the longest???

If anyone has a full size engine/w muffler drawing I would appreciate a copy.
