Catalytic converters

Ok, so again, the cut off is not 1974 here. It’s 1975 and older that are exempt. That means the smog laws apply to 1976 and later, 1975 model year vehicles are exempt.

I'm not sure what you mean by 'exempt' but the EPA made it very clear to us that anything newer than 1974 requires a converter that is equal to our better than whatever was on the vehicle originally. I'm referring to the sale of any type of aftermarket catalytic defeat devices....which could be simply a downpipe that eliminates the cat.

And thanks for all the other information about california emissions. I'll be passing this along to the staff as we get a lot of calls on this subject from Californians.
