Hey, what (other than number of cats) is different about a California '95 Fbod and the rest of the '95 Fbods? Is there anything?
In order for me to be street legal, with 2 cats, I need to switch everything (emmisions wise) to the Calif. style. So I am hoping it's just the two cats vs the one.
Anybody have any answers?
Thanks!

 

What do you have now? If your car was not sold new in CA, I would not think that you had to comply with what they did sell there (except for the performance test). I could be way off.

 

Not clear what you are trying to do. Do you have one of the CA emissions A4's with dual cats? Why would you have to comply with CA rules in Utah? Or are you moving to CA and worried that your single-cat "49 state" car will not meet CA regs? If, so, don't worry about it. In the past, they just charged you a $400 "fee" and let your car be tested to 49-state standards. I think someone might have sued them and got the fee eliminated a few years back... so you might want to check on the rules if you are moving to CA.

I would suspect that the programming in the CA dual-cat A4's would be different too. You could always have the PCM flashed by a dealer with the program you need, but I can't see any reason to change it.

Might want to clarify what you are worried about, or trying to accomplish.

 

Well, I'm wanting to go along the lines of LTs, 2 cats, Ypipe, catback, for my exhaust.

An exhaust shop guy told me that in order for me to be street legal, I have to have the same number of cats that it came from the factory with.
i.e. if mine came with 2, I cannot convert to only 1. If mine came with 1, I cannot convert to 2.

I asked him about the Calif. cars, and how they have 2 from the factory, and he said as long as I change everything else to Calif emmisions, that would work.

I don't know if he was thinkiing right, or what
another person told me as long as I have a cat, it is legal, no matter where it is.
I don't know, I guess I'll just go with 2, and screw the rest. If one place doesn't like it to pass emissions test, I'll go elsewhere.
Or maybe I'll go LTs, Ypipe, cat, catback. I don't know. Still throwing ideas around.
Thanks for your help

 

Look at your RPO codes. If you have NB6, then it came with California emissions and you should have 2 cats. If you have NA5, you have the normal Federal emissions package with 1 cat. The actual federal law states that you cannot change the location or the number of cats. It even says that you are not to remove a functioning cat to replace it with another. The laws are fairly strict, but the enforcement of them is another matter.

 

LT's will fail CA visual checks.

Dual-Cat cars are OBD-II, so technically, in order to comply with CA standards you would have to change the PCM also.

I don't think you will have to change anything due to the fact CA cannot override Federal Law & force you to change cats, etc.

 

Dual cat 1995 California cars are OBDI and I can't imagine any law making you change the pcm that the car came with.
