The DeLorean was manufactured to be 50-state compliant, which means that any part meeting the original specification (like a new old stock cat) would be legal in California. My guess is that the converter on the Special T auto site was not tested to the California Air Resources Board standards. It's expensive to do so and the makers may have decided that the extra expense was not worth the potential market. Which part you choose depends on how luck you feel. If you think your local testing facility wouldn't know an illegal cat from a hole in the ground, you can go with either part and hope that the new cat will perform at least as well as the NOS cat and you will pass your emissions test. If there is any doubt, I would go with the NOS part. -- Mike -------------- Original message from "sweitzel_2000" <sweitzel@xxxxxxxxxx>: -------------- > So I was noticing that Special T auto is now offering an aftermarket > catalytic converter.
