When i bought my used '12 700x it came with an aftermarket Danmoto can. one of their cheap ones. it looked and sounded fine but developed a crack at a weld , so I bought another brand off Amazon. Think I paid $60 for it. You could run it full baffle. the baffle w/o plug, or no baffle. I liked the medium setting. I was pretty happy with it , but I sold the bike so I can't attest to the longevity.
