California doesn't require the CARB certification anymore. As long as all the monitors are complete, good to go!

Now if you can't pass for whatever reason, and have to go to a referee, I don't know what happens then, if you don't have the cert.

 

The Magna flow is over $500 now. I am looking for something cheap I figure if I get one of the 150-200 cat/flex pipes I will still save my old cat. Then I can just weld on the flex pipe if the cheap cat doesnt last.

But the question is---which one. I live in NYC so I need one that meets code here, but several of the cheap ones do. Any suggestions>

Thanks again for all the help you have been

 

Just replace the flex pipe

I was looking to buy the entire part, including the cat for simplicity The repair section would be in case there are problems in the future

I was looking to find out which of the entire cat/flex pipes were good, or if anybody here tried any of them

Thanks again

 

I used this one

For the same reason, changed in a half hour, I have an impact gun. Changed the o2 sensors out from under the car

 

You better check with the "authorities", from the information I found NY requires CARB on your year. The 2 states that are NOT in the 48 state spec are California and NY.
Just what the interwebs say, probably wrong. $1382 is the cheapest I see.

Or we’re back to the clamp on flex pipe kit, and you’re old cat.

 

Or get a cheap one, and use it until your smog check is due. That would give you some time to get the new flex installed on your old pipe. This is under $300. Although I don't see a bung for the upstream O2 sensor. They have a flex section for sale separately also.

The first O2 sensor bung is there between the flex pipe and the catalytic converter

 

my car onpt has one oxygen sensor after the cat

Colorado also has the strict rules like CA and NYC.

Wonder what the difference is with the cats.
