MagnaFlow undertunnel questions

[yamakazie]

What are the dimensions of the muffler you guys are using? Are you having major icing problems with the exhaust fully exposed to the snow?

i had problems in the cold powder snow. going to change it this year and put a cover over it just so the inlet/outlet are exposed. mine is the 11214 magnaflow. i might try a multichamber to quiet it down.
