How are you guys making out with pipes on your 500's? I heard that having a power valve on the 500 you don't need a pipe since the valve automaticaly re-adjusts itself to the different RPM's thus eliminating the need for a pipe? I have an FMF gold series pipe that came with the quad when I bought it, but never took the time to install it thinking that it would not make much difference with the power valve! Any input will be appreciated.[img]i/expressions/face-icon-small-smile.gif[/img]
