If all the smog device connections are in tact on the header, then it probably won't throw any codes.

Technically, you should not pass the visual part of smog. AFAIK, hotshot doesn't look to get CARB EO#'s on their headers. You'll probably pass the chemical part though, as long as you replace the cat(see below), but I can't be certain as I have not seen tests done.

You only have one cat. It's just below the factory exhaust manifold. Underneath the car, there is a section that looks like a cat, but it is not. The hotshot header goes all the way down to this point. A cat made for an S13 will bolt right up in this dummy cat's place.

greddy makes carb exempt headers. i dun know if they make them for our cars though.

Wow, two cats? lol not stock, but with modifications, of course you can put two cats. It won't help exhaust flow, but i'm sure you'll pass emissions if they let you have two cats LOL
