i learned a lot from smog testing. Without it I wouldn’t have seen how injectors had deteriorated. Having to do the testing not fun, but there’s plenty to learn from test results especially if you track the changes over time.
Im not sure there are any test stations here east of the Cascades.

Pot / Kettle?
Tell yea what, I'll stop posting in emission related threads started by California residents if YOU stop posting in any emission related threads started by people who do NOT live in California. Deal?
How many times have you "warned" someone to keep their air pump for the day when every state is forced to follow California's lead?

I get to complain or not about my rules.

This brings back some not-so-fond memories of smog in CA.
I am not sure if it's the cats or not, but I had a shop do a TB/WP, cam gear, intake refresh, ISV, knock sensors, other usual stuff, plugs etc and it had single digits - passed smog with flying colors. I think it usually comes down to a few issues possibly compounding each other, not saying fixing just one could make it smog passable (such as cats).
The most frustrating part of the CA smog is even if it passes the sniff test (blows clean) if it does not pass the visual inspection it fails.

If someone thinks they have a solution, they can get it tested and approved.

Ya, agreed. The issue is that there are a billion ways that a cheap fix CAN run clean...for a very short time. With that much chaos that can happen in the system, its easier to set narrow achievable goals.

It's all about getting the SMOG cert! To be legal. Short side story - when I was a broke college student with an '85 maxima, I had cut out a bunch of the coupons for the 'free smog tests' from the penny saver. I eventually figured out that as I retarded the timing it blew cleaner - to the point of almost not being driveable though. I did eventually get it fixed though properly.
Going back to the OP, if you can sling the $$ for new cats, do it and consider some of the other maintenance issues. I was lucky in that my mechanic preferred I get the parts myself (from 928Intl - thanks folks) and deliver to him. Between all of the parts and labor, not too bad, about $5,000 with a couple of pit stops at a pub maybe on the way back from parts picking to ease the pain.

Ya...it can be a fun cat & mouse game. I just went thu that, but should be good for another 30yrs on a new cat.
I should log off the ST on a schedule, to catch drift.
