I have a 2004 660 raptor I'm looking to put a yamaha banshee motor on. Wondering about any mods. I know motor mounts have to change. But what is best way about pipes??? And I don't wanna hear anyone say, well why don't you just buy a banshee.... this is a winter project

 

I know this is a bit of a necro, but did anything ever come of this project?

 

I would have just modified the Raptor engine if I wanted more power. I'm sure the engine swap could have been done but I see it as pointless.
