Stephen's MC18 made about +2hp peak with race pipes I seem to recall, but lost a HUGE lump in the middle! I think it was dialed out in the end, and you can't argue with the looks of stainless steel and the weight saving, but it's not the be-all and end-all and I wouldn't chop my Ethos chambers in for anything!
