    Ive got 2 sets of some pretty decent headers that I got for free with a truck someone wanted gone. The guy was telling me they were smog legal (at least the one set) because they have that bracket thing that comes from the air cleaner. I looked at the headers and they had two little marks where the bracket thing was. Do I find a bracket somehow and weld it on and hope theyll go for it with smog? Or should I try and trade my headers with someone whos smog exempt for some smog legal headers? ...hint hint ;)

    They need to have an EO (Executive Order) number to be smog legal.

    Some parts have the EO number stamped onto them.

    Well first off it helps to know what year truck you have, and wether or not you have AIR injectio/smog pump. On my 81 and 86 K5 I had a smog pump and used Hooker headers that had ports for the AIR injection. It also included a crossover pipe to go 2 into 1 since my K5 was a single exhaust truck. I believe Hedman and Dynomax make similar headers. Some of the TBI trucks didnt have smog pumps so you should be fine with any shorty header that plugs into stock exhaust. My cousin did this when he cracked an exhaust manifold on his 91 Z71.

    I dont see any numbers or stamps or anything on them. Maybe I will after I clean them up and get rid of some of the surface rust. But I doubt it. :mad:

    It's 20 years old and still subject to smog inspections? I am so glad I left California.

    It used to be 30 years old and it was exempt (would have been nice I'd be exempt now) but then it changed to 74 and older, then 75 and older. I dont know when they'll work their way up to '77 and older but I sure hope they do. Fortunately on mine I dont ahve to have a lot of smog equipment like cats and o2

    I heard some talk that they actually want it to go back to 73-74. Everyone started hanging on to all the older cars waiting to drop huge motors in them. :D
