Am I right in thinking the exhaust port is 3/4" NPT? I guess they are standard on most motors. I want to swing by lowes and get some pipe and then swing by the exhaust place and get a stack made for the newly acquired cub 147 and if all goes well I will probably stack the other cub and maybe the mf 12.

I would guess 1 inch, but I may be totally wrong.

Yep, it was 1" NPT. I stopped by lowes on the way home and got a couple of galvanized 1" npt nipples and a 45* elbow just in case and then I swung by the exhaust shop and got two stacks made, one leg being a foot long and the other leg being about 2'-6" with a 90* radius. I got the stack mounted on the 147 already. I just gotta make a little brace for the vibration which I might do tomorrow.
