Can anyone identify these headers?
 

I got these headers cheap and can not figure out what brand they are. The air tube comes out the center of the headers. If anyone knows what kind they are let me know. Thanks

I've never seen a set with a single air tube like that.
But that seems like one of those, "DUH, why didn't GM do it that way?" moments.
So simple. Especially since the air injection was just to dilute the exhaust so the cars could get through emissions at the time.

Thanks Drew.

While Secondary Air Injection does dilute the exhaust, its primary function is to promote combustion of unburnt fuel present in the exhaust by adding additional air into the exhaust manifold and into the catalytic converter to help with the conversion process.

Yeah, that's exactly what GM wanted us all to believe.
They admitted years later about the dilution.
That's why air injection was removed when they switched to fuel injection.
