I've got a 2002 Yamaha R1 with the Scorpion slip on. I've also got the Scott's steering damper, K and N air filter, Pro-Tek rearsets, frame sliders, carbon tank bra, carbon fiber tripple tree cover, and other stuff that i'd have to get my reciepts out to remember. Yea, go with the Scorpion pipe. I like it. It looks good, cost is good, and it's rated as good or better than all the other brands. I tried to post a pic of my bike here, but the pic was to big. I could figure out how to resize it, but i could care less. I wrecked this thing pretty bad one day and paid for it out of pocket so my insurance would'nt go up. Fast and dangerous bike if you ride like me, heh.
