Woa. The cheapest set up is $4,665.00, without shipping or installation. If you add in the other stuff (Air Intake, Diverter Valve Kit, FMIC Pressure Pipe Kit, Heat Suppression) it's $5,235.00 for the 2863R. I dunno man... adding a beefier FMIC as well, and you are looking at ~7k. I would rather have spent that money and gotten an S4 will a tune and pulley and intake. K04 may not be as powerful or modern, but it's only $3k.
