I can tell you the turbo doesn't quiet up theses sleds a lot
Not a lot no, but it does make a difference on any engine if it has a turbo, it acts like a muffler. More power = more noise, simple physics. If you are easy on the throttle with a turbo and a can on a somewhat low boost level, its going to be manageable to keep quiet. I run my custom turbo engine with a straight pipe right off the turbo into the tunnel and I trail ride the sled, if your easy on the throttle it really isn't that loud in the snow. Sure she screams when I let those 300 ponies fly though! That's what I have found anyways.
