I am looking to buy some parts from a guy with a 2004 4.7 and I have a 2003 4.7. I know the s/c will work (piggyback the same?), just wanted some advice on the others. It is...Includes a new in the box UniChip controller, the Supercharger (also includes the original TRD controller), new Flowtech ceramic coated headers, new stainless JBA 'Y' pipe, 3 month old Flowmaster cat-back exhaust, 3 month old K&N cold air intake system. Also, what is a good price for all this? Thanks for anything!
