I have a set of Banks pipes here that i can't decide what i'm going to do with. They look and fit factory from what i've seen. At one time i think they sold the pipes/spyder for $550ish, but IDK if they still do. $1500 for a kit is asinine.
PDR made the best OBS intercooler kit. They stopped making them a while ago, but ya never know if they can hook you up with one.
85% of what you need:

All you still need to source is an intercooler (fairly easy).
Just got a phone call back from Travis @ Bar None Diesel.
He said they are working on getting some more in, took down my info, and said he would let me know as soon as he got some info on a expected date. Seemed very willing to help as I was willing to buy today had he had them on the shelf.
