94 pickup exhaust manifold cali smog check

Newbie/non-mechanically inclined person here, hello! My 94 pickup's 22re has an aftermarket exhaust manifold which won't pass visual inspection for california smog check. i located some oem replacements on ebay and various salvage yards but my mechanic is saying that i need to be careful that the part is california made. i asked him, "did toyota actually manufacture things differently in 1994 just for california?" he answered that basically you never know. i found a site that says all 22re engines were made in california in 1994 but either way, isn't an oem exhaust manifold enough for passing smog, regardless of if it came off an original california truck? just being extra careful so i don't stuck with useless exhaust manifold!

Can you post a picture of what your truck has now?
As far as I know, all exhaust manifolds in 94 were the same on a 22re. The difference is that the CA exhaust has two o2 sensors on the exhaust pipe, one before and one after the catalytic converter, and the federal trucks only have one before the cat.

I'm pretty sure the earlier trucks had a different style manifold that had a sensor in the manifold itself.
