As of January 1st 2009 all OBDI catalytic converters will be illegal

shumby

As of January 1st 2009 all OBDI catalytic converters will be illegal for sale in the state of California. Period, no if ands or buts, no loop holes.

Bottom line, since magnaflow/carsound is located in California they will not be able to sell the cats to anyone in California. None of their dealers will be able to sell to you if you are in California. Fast Intentions will not be able to sell to you if you are in the state of California. I know it is short notice but if you are in California, you have one day to buy cats. After that good luck.

The good news is the other 49 states in this country do not fall under this law. This is coming down from B.A.R.(Business of Automotive Repair) and CARB.(California Air Resource Board)

I just thought I should put this little bit of information out there for all of you.

Fine, I'll have my company in Texas buy it and ship it to me. No big deal.

Doesn't Cali have routine emissions checks? Won't they check to see if the proper cats are installed?

Yep, that's the only reason I don't have them on my car right now.

I think the hypocrisy in the fact that the person responsible for these air pollution laws (Schwarzenegger) is famous for driving Hummers and smoking cigars is mindblowing. Of course, we've seen how much respect his wife has for cell phone and handicapped parking laws, so I'm assuming he probably has a fleet of sports cars that would fail them miserably.

^ CA does have routine inspections which includes a visual inspection plus tailpipe test. As long as your CEL isn't on indicating a CAT failure and they see that there is a Cat behind your exhaust manifold, I doubt you would fail the test given that the emissions would probably still pass the tailpipe. Do you know if the aftermarket cats have their brand stamped into the cat which might tip off the mechanic that its not stock? I.e, does it look stock?

They do but that happens every 6 yrs after the vehicles purchase. So there is some time before you have to worry about that. All you have to do is keep your stock manifolds and cats, put them on before the test, and u are all set. Also even though OBDI cats are illegal, you can still get them installed from various reputable perfomance shops like SP Engineering or Technosquare and buy them out of state.

Ya that is the only way to get around this for you cali boys

Cheaper for them to buy out of state anyway with no taxes due on the product.

Majority of our customers are out of state.

Damn Cali laws keep increasing and getting more strict towards vehicles... teh governator!

(New member re-opening thread What does OBDI stand for, dude? Pardon my ignorance, but I'm sixty, and enjoy driving my Z; still, I'm an ignoramus on some of the acronyms used here. As a humorous note, the 1st time I read "FI", I thought it meant Fuel Injection! Now I know a few: OEM, FI, even LOL! Thanks for your patience with this old man in love with a Zed!

Time to get a UPS address in a city outside of CA, and have them auto-ship it to your address in CA

Thanks, ctzn-man! Now why would CA wanna do something like that? What's the disadvantage they're trying to overcome by banning them?

If I recall properly, the actual catalytic converter design on OBD 1 and OBD II are not that different. The difference is not in the converter but in the computer controls monitoring the converter. On OBD II, the ECU is able to detect a failure in a converter and throw on a CEL whereas with OBD I, a failed converter will not be detected. It works as follows:

- On OBD I, the oxygen sensors are placed only before the converter in the exhaust system. It functions to adjust the A/F mixture based on reading the exhaust output.

- On OBD II, it still has the front sensors which are necessary for all computer controlled Fuel Injected cars but in addition to the front sensors, there are also O2 sensors behind the converter. The backend O2 sensors are not used to adjust the A/F like on the front. It compares the "filtered" exhaust air to the pre converter "filtration/gas conversion" reading per the frontend O2 to see if the reading has changed significantly. If it has, the converter is working properly. If the readings on the front and back 02 sensor are similar, this indicates the converter isn't properly converting exhaust gases into less harmful ones and puts on the CEL for converter failure.


Technical issues aside, another change enacted by the new CA requirements is that you can no longer select a converter based on the vehicle size. You have to follow a specific application chart for each car. I'm not sure what criteria has been used in determining the appropriate app.
