Manual showed up, thanks very much.
I plan on inverting the muffler, run it straight down. The fittings look like it will work alright.
Managed to secure turf tires, will pick them up next week.
Found tire chains on kijiji for $60.
I may stud the rice tires to see how they work in the winter.
Switch to the turfs if needed for winter, definitley switch come spring.
Still haven't told my wife I'm spending $800 on tires.
