Is a stocker out of the question? If you've already got a cat, you might try running some Gumout Regane or some kind of fuel system cleaner and carbon remover through the system. Also, put a new set of plugs in and make sure the timing is dead on. All that will sure help.

Unless you've got some fire breather with poor fuel management, I would think most any new cat would do.

 

From what I heard hi flow cat is not good for smog because the flow rate is high and it doesn't allow enough time/surface to clean the exhaust before it leave the cat. Another thing to notice is if you are using a low quality cat it may not last as long. If stock cat is not so expensive I would recommend stock cat ($600 plus).
