Catalytic converters

Since you asked, I've worked for an environmental regulatory agency in California for the last 15 yrs. You can probably guess which one. Needless to say, I correspond with my EPA colleagues on emission-related assignments regularly.

That's irrelevant though. As a gearhead in California, I was simply pointing out the blatant misinformation in your post when you said "If your car is 1973 or older, you do not need to add cats to your car except in California." That's absolutely untrue.

I have no idea why I put 'except in California'. :( Well that's embarrassing. I apologize to viewers.

I might have been thinking about the original 1967 EPA requirements. ie smog pumps and the grey area of wording that accompanied those initial requirements between then and 1975?

Anyway, those are some pretty good credentials! :thumbsup: I've participated in automotive forum communities since 1991 and have experience a multitude of self proclaimed experts that turn out to be spreading a lot of bad information. And now I'm one of them.:BangHead: Luckily through participation, the good information almost always bubbles to the top.
