I had a problem yesterday getting a muffler shop to install this cat I got from magnaflow because he said it wasn�t OBD-II legal. I know he didn�t know what he was talking about because I knew it was, he was looking for a sensor plug on the cat and I tried to explain to him even on the stock cat there isn�t one.

So I called Magnaflow wanting to check out to see what the recommended cat was for a 98 CSVT and he told me a 91000 series which was good because I have a 91006. Then I asked if it passes CA regulations for a cat. He said they have not been cleared yet by CA and there was no other cat you could buy for your car besides the Ford factory cat at the moment that would pass CA regulations.

I wanted to know if anyone has changed their cat to an aftermarket one. Also if they have, then have you passed smog?

The magnaflow technician said that those cats have not passed through CA regulations yet, but could in the future.

Thanks for the help.
