I've been kind of wondering this as well.
I will have 2 intake/injectors/rails combos, one brand new zero miles off the aluminator, and the other other one barely used, for sale if they're worth something.
Its called your return to stock pile, i got mine in storage! I got oem headers a couple of oem drive shafts, oem airbox, oem mufflers, panhard bars, springs-2 sets, sway bars, 18 inch wheels on p-zero tires....the list goes on...maybe a good idea to buy all these parts from folks and sell them to dealerships who need to put modded trade ins back to stock for sale...lol
