2006 MPV Catalytic Converter Bank 1 for California
Looks like my bank 1 catalytic converter (front passenger) is bad. Muffler shop says parts aren't available and dealer parts store says Mazda doesn't make catalytic converters for that year and model anymore.
I'm going through the California smog referee process now.
Wondering if any California MPV owners had to deal with this situation. Muffler shop can't weld on an after market. Online dealers won't ship to California. It's illegal to buy a used cat (e.g. from a junk yard).
Also, has anyome installed a bank 1 catalytic converter? Looks tricky in regards to access since it has six bolts that connect to the under side of the engine manifold. Did you have to remove any parts or lift the engine? Or can you access from underneath with a very long extension?

Welcome to the forum
There are 2 things you can do... which I am sure was explained to you...
Get an exemption because the OEM is no longer available and a CALIF approved CAT is not applicable for your Mazda
The other way is a muffler shop CAN weld in a new CAT legally if you first remove the exhaust pipe and take it to them. This is a simple labor welding and as they are not seeing or knowing the vehicle (they should not ask) there is no Ca regulation restricting them from doing that welding of a part.
Once the new CAT is installed your ECU monitors should all be in state of readiness, and you should have no problems passing the biannual emission testing.
Word of advice.... it would be better for you if you can do your emission testing at an independent Testing shop instead of going to a State Emission test site. The independent emission testing is privately owned and all though they do all the requirements if your ECU is not registering any DTC pending and the monitors are, or they may or may not need to tail pipe stet you. But with the CAT in place, you should pass that anyway. And visually I doubt they would see any indication that you have a non-OEM or CA CAT on your exhaust system.
I was CA emission certified as a tester up until lasted year when our shop decided not to invest in the upgrades required by the state of CA to do emission testing. It was not worth the money vs the GP that may have resulted.
BTW.... San Jose Ca is a great 3 hr drive to Reno Neveda where auto parts stores have plenty of CATs to sell.

Then if your information from the California Emission Testing site is giving you the correct informatio9n to locate an approved CAT and there is none available then you can file and get an exception.
Other wise you will need to travel outside of CA if you want a replacement part that is not CA emission qualified. I can teel you if you do that it will pass the visual as well as the tailpipe test if it is done and also if installed correctly should meet the input sensor information from the H02 so as not to cause a DTC.
The other problem in CA you can't even sell your MAZDA or any other vehicle that has this problem and you are not likely to be able to transfer a sale to someone in another state with a CA open emission requirement?
Ok that about all my advice on this thread, good luck

That said, if I put a little bit of gasket maker on the gasket to temporarily hold the gasket to the cat while I bolt it into the engine, would that cause any problems later? I'm ok with the gasket maker breaking down if it doesn't cause problems with the cat.

Guess I need to make some calls to NASA.
