What do you mean, I wouldn't know what to do at 14* below zero?! I know exactly what I would do. I'd move the tractor into the house, and set up shop right in front of the fireplace!
I played with the exhaust a little today. I temporarily put the ugly hood back on for test fitting the exhaust, and once I had it where I liked it, I welded the muffler to a piece of 1" pipe, so the muffler will just screw on. Hopefully I'll get the time to paint the hood, fenders, etc.. this weekend.
