I'm also in Utah and have to do the annual testing. That's why I keep my stuff to re-install each year. There are plenty that live in no-test counties though that delete and sell their DPF/EGR kits for $500 or so. Just start searching KLS classifieds. Search key words like F-250, F-350, F250, F350, Super Duty, Powerstroke, 6.4, etc. I've seen plenty of them before.
Then just swap the stock parts back on and go get flashed at the Ford dealer. Do you plan to keep the truck running stock then with no deletes? If so, you may highly regret the 6.4 purchase as it will only cause you problems in the long run. If that's the case, then you may just want to lawyer up and try to get your money back from whoever you bought it from for undisclosed mods. Plus, when you purchase in Utah the seller is supposed to give you a recent within 60 days emission certificate. Did you not do that?
