Thats a good sale, NW modded were $699 plus ($500 core charge). I didn't want to give up my stock manifolds and am not a fan of the "teflon" velocity coat that they use.

Mine are ported, more like polished. Truely there is not much porting to be done with the exception of gasket matching, it's very little work and unless your going to work the lowers then you haven't gained very much. The real gain is from cutting out the restrictive piping.

My total cost included the used set of AMG manifolds that I picked up for the project, so I still have my SRT-6 manifold for the future.
