The CA DMV just recently sent me a letter stating that I need to smog my 92 F-250. I told them it was a diesel and was exempt from smog due to the age of the truck and I didn't need to, they then required me to have the truck inspected by their "trained" official who had no idea what he was looking at since I had a Banks kit on it. Thank god for Banks placing a C.A.R.B and E.O sticker under the hood or I would still be there fighting with them. Just make sure you do your home work before you start the project so your not sorry in the end.
They just sent a letter out of the blue?
