Hey guys, I know by now without a pipe I'm out of the game. I can adjust one for a bike to suit. I was just wondering if you had time if you could post the length and max diameter of a competitive 125 Mc hotsaw pipe. If you cruise expansion chamber on ebay there is lots to choose from. Many looking suspiciously familiar. If they are plentiful and relatively affordable maybe I can just buy one from somebody? Thanks Jared
