Default High Flow SMOG Legal Cats

I am looking to buy some cats that are legal in california and have a carb number. I know kinetix has some but anyone know any other companies who offer a similar product?

AFAIK, it is illegal at any point to replace OEM cats with another brand/type of cat unless it is OEM.

You can consider NISMO to be OEM

** Please check local laws regarding catalytic converters. These pipes have passed visuals and sniffer tests in CA (the strictest state on emissions) but they do not have a CARB number associated with them. **

NOTE: Replacing the OEM cats with test pipes, aftermarket high flow cats, or modifications of any kind to the OEM cats is ILLEGAL!

2 notes that I found using the link above. I believe that even if you damage your cats, in California, you must replace them with exactly the same cats. Many Z owners here have modified with test pipes or high flow cats, and I do not think that this is a "fix it" ticket any more.

OK - so here's the real skinny all -

In Cali - you need OBDII certified cats - and the only ones available are your OEM CATS.

CARB numbers are great for Cali - for things like headers, but not for CATS.

Keep in mind - you may pass a sniff test or visual, if the tech doesn't look at them at all.

That's the fact jack!

Also--Federal Law--I don't think you are allowed to swap out cat's under federal law until 50k, if they are working.

You can swap out anything as long as it is relaced with approved and certified products, of which in this case, there are none.

I don't think NISMO cats will be a problem. They look OEM anyways.

No such thing as a SMOG legal cat besides the OEM. Not even the Nismo ones are legal.

I passed with Random Tech hi-flow cats. There are certain restrictions to changing your cats in ca but its safer and better for environment if you have cats as apposed to straight pipes. No check engine light either.

Fast Intention HFC or TP. Who cares about passing smog tests. Just swap the cats out when the time comes

So why are HFC's illigal in CA if they pass the sniff test and asuming they meet sound DB levels?

Never made sense if they pass the sniffer why are they sooooooooooooo/illigal bad to use.
