Heres the deal, I'm putting a CR500 in my 400ex frame and am wondering what pipe to go with. After looking at several I have decided that obviously a 250R pipe will fit the best allowing me to make very few mods to get it to fit. However I am concerned with the flow numbers. Obviously a 500 will need to breathe more than a 250 so is there a particular pipe or brand that flows more? What should I be paying attention to when modding the pipe to fit my frame. This is my first two stroke so I am not well educated on the pipes and how they affect performance. Any and all help is appreciated. -Trent
