M8 Megatron----I assume you are adding a Super Q to the 2008 listed in your signature? (can't compare with the 2010 video posted---not the same engine or can design)
I found out by accident on my 2008 that the Super Q, even for the older sleds, has been redesigned and looks EXACTLY like the Ultra Q from the outside, just less baffles inside. Western Power Sports still has the OLD picture of the Super Q in their catalog, so I thought I was getting an Ultra Q and it would be too quiet. After talking directly with Skinz, I found out they redesigned the Super Q partially due to complaints that it was too loud. SO---I do not like the sound from the newly designed Super Q on my 2008...not loud enough. It's barely louder than stock and really doesn't have the high-pitched scream even at wide open. I was paying for good sound and weight savings, but only accomplished weight savings. The new Super Q is so close to stock sound, I can't imagine there being another step below this---the Utlra Q.
