Kansas City is a long ways from Garden City, but I had one of the forum members called Area47 tune mine. He's good and might be worth the drive. Once the headers are on, you will probably get a check engine light, but as long as you drive normal and don't do any wide open throttle action, you'll be fine to drive it. I installed coated Pacesetters and have been happy so far. Obviously, stainless steel would be less rust prone.
