stretching a 155 to 163

[TIM]

I am thinking of tradeing my sled in for a rmk 155 and putting a 163 under it.
i would get the rmk instead of the pro for better cooling.

But does polaris have a tunnel extension for the 155 to 163?

Seems like it would be alot easier to add a cooler oppose to changing rails, track, adding tunnel extension etc...

not to mention you would probubly be voiding the warranty. With all the bent tunnles and running bords, it is something to consider.
