OBDII CARB compliant cat?
 

I was looking at getting a 3" OBDII cat. I was reading the description and I noticed this one is OBDII but it excludes CA.

Would you fail someone for having something like this? ...I hope you are the smog tech guy. Haha.

And what would I/ you look for to make sure it's CA legal?

I know a guy that won't even look. As long as it has cats and passes the sniffer you're good.

In CA you cant go with any cat that isnt stock to that car....Thats why long tubes are a no go for CA

There are now Magnaflow OE replacements. But I think there's technically a required process of a smog tech practically signing and affadavit as to why you need them.

LTs are illegal even if you get the OE cats on them (fabbing). As I recall it's primarily because of the resulting "relocation" of smog equipment: cats and O2 sensors.

kdracer will know the details or if I'm total full of shi*.

I wonder if I can cut the stock 2 1/2" cat in half and weld the shell around a high flow 3" one.

Sean, does your guy charge more?

Same here, my tech will just shove the sniffer down the tail. Doesn't care how outrages your mods are as long as you pass. The way it should be....

No :drink:

Is this guy a test only tech?

I dont think i've ever been to a smog tech that has ever cared about whats under my hood as long as it pass the sniff test

Yes.

Wow.

page 4 of this doc gives the guidelines of inspection/ID of installed cats

I have had techs who would not test me because of the headers on my SHO. None has ever said anything about my custom y-pipe with the magnaflow cats.

The new spec took effect Jan 2009. If they where installed before the rule change..grandfathered in. The cats will have a date stamp they are supposed to check.

I used to get a cat, pre obd2, installed , for 120 bucks. They are outlawed now. My cost installed on my daughters 87 Volvo was 300+ bucks

Magnaflow does make OBD2 certified, carb compliant cats. They do come with a form ( carbon copies, in triplicate, no less ) That the installation tech has to fill out for you, basically saying that the car is A. old enough or B. has enough miles on it to make getting a new cat beneficial, and then you have to keep a copy of said form, as does the shop, for perusal by agents of the nanny state.

They are actually fairly affordable though, surprisingly. I can get pretty good prices on them generally through a supplier we use at work, so let me know and ill see what i can do. (Just need a general application, pref. make model, but can also use dimensions )

Basically the car Im looking at has an offroad 3" downpipe. I was hoping to weld in a 3" cat and make it legal, rather than having to swap the 2.5" stock pipe in.

I wonder if I could cut the mouth of the stock cat open a bit for the 3" pipe. Dumb idea? Think they'd pass it?

all depends on the tech. they could definitely fail you if they see a non-stock cat in there, if you dont have the requisite paperwork.
