Yup, the pipe on the bike in those pics was the first attempt. The pipe I'm building is the 2.5 attempt, and its freaking HUGE compared to that first pipe. Had 2 MB5's for a while, fun bikes! The first attempt was designed with some web flash applet thingy. This second one I did buy the build and click 2 stroke software. Seems to work great, really like the cone layout printer thingy that comes with it!
