update on the blower heater for the rzr 

Thanks for the idea , I was looking for some type of flange to mount my computer fan , it has lots of power and seems much quieter going to use a 3x10 x4 boot strapped over header , flex to the fan on back of the access door

Yes it's loud but better then freezing cold on the trail.use ear plugs.

What kind of blower did you use and where to get one

Heat from engine exhaust?
