HI Vern, I have the full kit on, intake, headers, and exhaust. Remapped the ECU as well. Truck runs great makes more power and my gas milage varies with how I drive. I used the long tube headers so I had to cut and weld. The dealer is uding the shortie headers now because of cat failures. The Belinger headers that they were selling for 2500 burned up the cats. Besides they are not worth that kind of money. I used AZ Speed and Marine headers on my truck at a fraction of the cost. I put them in myself as I enjoy wrenching. Infact I did all the mods myself. I don't the dealer touching my truck. Anyway, I hope to hear from you.
Randy
