Well if you were ever curious about how some slip-ons sounded; maybe because you may buy one in the future or whatever, then check this out site out. It's posted on other mc forums so I might as well post it here too.

I like the Scorpion. I'll probably get it after I get more gear, buy a steering damper, and do a track day or two. It's nice to get one for the sound but it's just not on my priority list. I rather spend the money on better gear and helping myself be a better rider.
