My xj has no cat on it, and no evidence of one ever being there. Was there such a thing? Were California state service jeeps sold to the state with out cats?

 

No, and you need to have it re-installed

 

I suspect any vechicles sold in California, were the first on Earth to have cataclysmic converters.

 

I think it was in the '80s that all vevicles were required to be equipped with a cat. Someone probably straight piped it and got bored of the cab noise.

 

Every vehicle produced after 1973 was equipped with a cat from the factory, unless specifically designed without one (SRT-4 neon and others). My 89 has a cat, so your 90 probably had one originally also. Technically you can get away with it depending on where you live, but most trail sites will turn you away for it and it is still against the federal law. For me, I just have to have something resembling a cat and a muffler because I'm exempt from emissions from having a vehicle produced prior to '95. I still get a visual inspection for leaks though. I'm sure over there in Cali. there should be a cat on there.

 

Haha yep. Get a cat on there buddy

 

EVERYTHING after 73 has a catalytic converter, no exceptions. That includes SRT's. SRT 4s have cats, resonators, and no mufflers

 

Cats weren't required until 1975, although certain '74 GM's had them.

 

Converters were not required, they were used to achieve emissions numbers. I have a 1977 280Z, 48 state, Regular (leaded) fuel, Non-cat via the emissions decal under the hood. I'll add a pic in a while.

 

Next year California residents will have to wear pants with attached catalytic converter.

 

Ugh. At this rate

 

Put one on.. end of story. Call this thread done and go on with your day

 

 

If it was originally shipped to a country with no emissions laws and only leaded fuel, it would not have had a cat.

 

My 76 Chevy PU came from the factory without a cat.
