Yes but it was coming from the exhaust manifold

I hope I'm not being dense, but where else would it be coming from?

Well normally it comes from the tailpipe but since it's coming from the exhaust manifold that means its cracked/leaking and needs to be replaced/repaired

You seem to doubt the cat, judging by the question mark.

Instead of buying new while not knowing if it even cures the problem you may try this:

It has been 20 years since I moved, but isn't there a process where you can get a 1 year one time exemption?

You can braze the manifold cracks for a short term repair. I haven't had a lot of success with welding but the brazing I did lasted many years. I have also used 3 gaskets and longer bolts, and a roll of exhaust fix it tape.

You didn't indicate whether or not you did anything major to repair before secondary smogging.

CA won't allow tape on intake manifold (or exhaust) but brazing is allowed. You cant weld cast iron I was told by a experienced welder (on a Suzuki sidekick). I couldn't source an exhaust manifold any of my sources. Some of the newer expoxies would probably work. The crack is no doubt making a lean(irregular) reading at O2. No smog here in southern OR. You pay in smoke when you get behind the logging trucks(injection pumps are turned advanced. I guess carb legal header is big bucks (maybe a used one.. I have everything but e/manifold and ecu for vx. I would check jdm engine
importers and Picknpulls.

Change your oil. My saturn failed and I changed the oil and it passed. Lots of HC in old oil.

Use a nickle electrode to weld cast iron. Epoxy wont work.
