I couldn't care less about making noise, but I detested the stock can the moment I saw this bike in the magazines in 2007. As soon as I could afford it, I went for the quietest and, to my taste (my bike), nicest can I could find: a Remus Hexacone. Just amazing, subtle while cruising, baritone when opening up. And the 1 HP extra (Remus claims +2.5 HP, magazines measured a bit less) combined with the 10 lb diet, just round up the subjective pleasure I get from it.
