If you go to this site http://www.oohva.org/pages/sound.html

and scroll down you can select your brand of machine, then it goes into all the different aftermarket and stock DB levels for all the different quads that brand makes (although not all models, but most)
I have seen numerious posts asking about how loud is this .... versus this kind, and so on.

Maybe this will help
