Which Ending of Wrong Turn was this???

I can't keep track of all these Wrong Turn movies anymore but I did remember one ending scene involving a girl who survived and she was running out in the snow. I think she also got on a snow mobile and finds another friend of hers along the way.

They're both riding to safety when suddenly they rode into something that decapitated both their heads. The head goes flying in some comical fashion. I don't know if I'm asking about the same movie or some other movie. Does anyone remember a scene like this?
