Intake and exhaust options

[keith fraser]

I see Factory Pro has a "stage 3" jet kit for the GPZ, but can find noe listed for Dynojet. Anyone have any #'s for stage 1 vs 3 with the GPZ, or any other considerations when weighing 1 versus the other? How about exhausts? I am kinda stuck between V&H SuperSport(best price, but no dyno)and Micron(decent price,decent dyno #s). Anyone have a dyno sheet for a V&H Supersport equipped GPZ?Thanks for the input so far!
