Ok, in Pierce County you will have to go through the sniffer. If you guys were to move south of Tacoma, you would be fine. They still dont do the sniffer in Kitsap and macy counties. You will need to get cats back on the truck and have to have it tuned for passing the inspection. He said the tuning out there for that would cost around $150. My advise would be not to register it there if you cant move to a county that doesnt have the sniffer..
