    No doubt.. it's a factory five setup. Never hurts when we get to dream and live vicariously through another guys wallet, eh?

    It's far beyond my kids college fund savings. :D

    just picked up a set of QTPs.... getting them installed next week. If anyone has tips on placement it's appreciated. I am running Doug Thorley headers.

    Thanks
