Some information that I've been told from a legit exhaust shop (they weld custom roll cages for rally cars, track cars, basically anything) is that the legal replacement cats are almost on par with hi-flow cats now. You can take one of these, cut off the stock diameter piping and open it up a little and reweld 3" piping on it to fit your exhaust, and it'll be 100% legal. It'll have all the correct serials, CARB #s and whatever else that these cats are stamped with. These guys don't do anything illegal in their shop and will not do anything off-road only unless the car comes in and leaves on a trailer. They told me shops are still liable for the work they have done to the car if the illegally modified car drives off their parking lot, no matter what warnings, waivers and anything else they do to try and protect themselves. Just an idea for anyone who wants to take the safer road.

But back on topic, I'm assuming these places don't have AWD rollers, since smog still doesn't require shops to have AWD rollers. I wonder if this means we have to automatically refuse and get logged into that database?

They designed things this way to take rights away from people who like to modify cars, which is stupid because Cadilacs ctsV's and shelby mustangs pump out way more power and probably way more emissions than a modded subie LOL .......What comes out of the tailpipe should be all that matters

Thats surprising, I figured a supercharged V8 would put out more emissions haha common misconception i guess.

You can be cited for out of state reg while living in CA, You can be cited for exhaust.

My uncle lives in Vegas and he has 3% tint all around.

When he visited here, a police officer pulled up right next to us and was trying to look in the car and then he slowed down to look at the plate but never pulled us over or bothered us again. He told me it happened 2-3 times driving up here and yet he's never been pulled over for it.
