Gypos 066 JDHotsaw is actually a winterized version with an expansion chamber and that is how he creates all the ponies...he runs the exhaust into the handle bars, using that as an expansion chamber and keeping his hands warm...the exhaust exits the handlebars on the bottom right side keeping that leg warm as well...
Dont tell to many people about this, or they will be lined up at the gate.
I have 2 440MS Arctics, and 2 MS460 Arctics, c/w 16" bar, never used, for $775 and $825 respectively + delivery. It doesnt get any better than this.
