quick question stock exhaust manifold help
 

Hey guys im new around and have a pretty simple question to drop. i have a 96 camaro lt1 and i live in cali (smog bs) and i need to know what stock exhaust manifolds will work with my setup. is it 95-97 only? i heard the 93-94 1's are different.

smog stuff sucks here because i had a nice set of hooker headers before. Now i just want to run stock so my motor swap project can get a pass by the smog police, i mean referee.

I thought the only thing that changed was the specific single cat or later dual cat y-pipe and that all of the F body exhaust manifolds were the same. Hopefully someone can correct me if I am mistaken.

I think the AIR check valve threads changed on a couple years. But all 96-97's should be the same. Only the California cars in 95 came with dual cats.
