I am glad you said that.. I had been wondering what made the noise - Not worrying, but noticeable.
I bought one of these in the UK for the equivalent of six bucks. Haven't fitted it yet as I have modified the std 2003 arrangement and that seems to work quite well so far. Was worried the longer exposed duck bill set-up might make a right ol' mess of the rear end. From what you're saying this isn't so?
