well for all you guys wondering about installing a bd manifold here ya go. very straight foward. i did this at work on the lift so keep that in mind. but is spent little over and hour to install. removed the tire/wheel and took out the inner fender. took lower intercooler pipe loose and pushed it out of the way and took the steering shaft loose. spray all the bolts down, the three back bolts are very tight had the double wrench them out. have not driven the truck much since the install but noticed maybe a 50* egt drop on the way home. just thought i would post my thoughts and let you guy know it is pretty simple install.
