Well, if it was intentional, (and I tend to think it was) I hope you are right about that bell going off for the designer. I have always liked the look of the stock can and it's note is decent too. The beefiness lends itself to the character of the bike imo. Anyway, still looking forward to trying out that Ago hydroform or Termi someday.
I can see what you are talking re. the frame demonstrating a bit of that winged logo curve odder..
