Paul, i picked up a BDE Gen 3 ( stepped ). Real impressed with the sound so far. Not too loud by ANY means. I was on my buddy's 05 R1 today with modified stock cans and he was on my Busa. He was in front in rolled the throttle on my bike and i followed suit on the R1 and i could hear the exhaust of the R1 over the Busa. SOOOO, i had him come from behind me and i stayed at about 3 grand on his bike. My busa went flyin by making oh so sweet music. You should'nt be disappointed with the Hindle. Power seems decent as well.
