I think it's entirely to do with the design of the heat exchanger on the cat. Nothing running down the tunnel. The only downside that I have found is that you are going to need scratchers running up a long trail like Renshaw unless there's fresh pow on the trail.
What are the options for scratchers on the alpha? I'm guessing just the ski mount type?
We have the reversible ski mount scratcher in stock if anyone feels they will need them. http://www.sourceinnovations.ca/product/reversible-ski-scratchers/
