I've got an 80' p/u with the 20r and 22r hybrid and i'm trying to get it smogged. And could use some help with making sure it will pass. However i have a header and was told that it was an illegal header, but it is also a nevada vehicle and im in california but i've been told that the smog is a federal smog even though im in california. Anyway im wondering if anyone has had theirs smogged? Because i'm being told that i need to replace everything with all 20r parts. Any help would be great.
