I am thinking about scraping up some money and doing my own YZ450 pipe shootout. I'm a little curious myself, but if nobody else wants to hear my personal results then I won't bother spending all the time, money, and effort in doing so. My goal would be to take a bunch of pipes (Ideally an FMF, Pro Circuit, White Brothers, and Dr. D) to a track and ride a couple laps with each one and report my findings. Let me know how much interest there would be. It may not be for a little while if I ever end up doing it (probably a couple months to get all the pipes).
