I got the truck in September, at home I had a Gibson Extreme Dual cat back system, an Air Raid throttlebody spacer & a Volant Cool Air Intake, great on the gas milage, I average 19.3 mpg combined highway & street, stock it was getting a little over 15 & if you step on it you really feel a difference. After a few weeks I found the tail lights & projection headlights with angel eyes on E-Bay. The audio/video is all by Alpine except the unit on the roof which came with the truck which is by Panasonic. It took some work but I got the the roof unit to work with the headunit TV. Hope you like my ride so far, coming soon: Chome & Black 22's, a 2"-3" drop & a power programmer.
