I need to buy some exhaust manifolds for my '76 to replace the headers that came with it. My question is this: What is the copper tubing that hooks into the manifold called? I can only find manifolds that don't have this piece installed, but I am going to need it in order to pass the smog test.
I've heard them called smog tubes (logical, huh), you'll also need an air pump (belt-driven), a diverter valve, and I think some other miscellaneous hardware.
I think you'll spend the least on the best parts at a salvage yard, most of the components except the manifolds were used on millions of vehicles.

have you checked out the C4 manifolds? i seem to recall they flowed really well and i think they have bungs in them so you could probalby plumb anything you needed
I have looked everywhere to find a set of the A.I.R. tubes for my 80 and finally said the heck with it. I have plugs in the holes as we don't have any emission requirements in my state. I would like to buy a set myself and keep them with everything I removed from my car, just in case I ever give it to one of my sons. they live in California and would need to have everything that the smog natzi's require.. If anyone finds a source for the correct tubes for a 1980, please post the source or pm me. I bought a used set on evel bay, but they are a bit grim. I guess I could get by with them if need be, but I would really like new ones. Sorry, I didnt mean to hijack the thread.
