the jim wolf is the kit i would get first also, i like the twin intercooler setup making use of the stock front bar (because i am retaining it) but the problem is, that, JWT will NOT sell the kit to anyone unless one of their authorized installers installs it also.
its kind of like how APS only sell / install the kit in the same price in australia and you cant buy the kit seperate.
only way is to find someone who is selling it 2nd hand
