Catless headers are not allowed. Reason being is because under the visual inspection we need to input modified for the visual catalytic converter test. So its not about emissions its about the visual.

For readiness monitors.

2000-newer cars only EVAP monitor can be incomplete for car to pass.

1999-older only 1 monitor can be incomplete for car to pass. either monitor is fine.

Some counties dont require dyno test which are areas that have only basic testing and not advance testing. Major cities are advance testing which we use dynos. But since the Smog program changed in the summer its completely different.

How do I know this.

I am a smog tech that has a shop. thats all

The thing is I just bought a new CATBACK exhaust and was just about to install it and came across this thread and scared the crap out of me.

Catback is fine so dont worry

Good luck with that...

we dont do emissions testing on 2000-newer cars anymore.

Wow, no wonder you're resourceful. That's cool that you own smog shop.

What about aftermarket secondary cats, ie the one found in the mid-pipe? Will that fail visual inspection?

Aren't newer cars smog exempt for like 5 years? So like a 2013 would be good until 18/19 just pay registration and abatement fee?

Lemme clarify this....well, see if I understood right.

On our twins we no longer have emission (tube in car exhaust) part for smog?

If it has a aftermarket secondary cat in CA it must have a CARB label on it. If you change it with a cat that isnt carb legal and has a carb label on it then no its wont pass the visual.

new cars off the dealer lot when bought brand new are smog exempt for 6 years. But if you bring a car from out of state doesnt matter what year or mileage you need to get it smogged.

thats correct. 2000 and newer cars dont require emission testing

So everything posted on http://smogcheck.ca.gov/ is false?

Edit: I am not doubting what you are saying. The last two times I've had to smog any car, both have involved tailpipe testing on a roller dyno. Both were within the last 4 years.

I believe the way they do smog has changed within the last year

State changes rules yearly. They came up with the DAD System (new smog machine all shops had to buy) in June 2015 and ever since then it has been that way.

I recently smogged our 09 mazda3 and it was able to pass with a non-CARB aftermarket second cat. Maybe its because it looked stock or the place I went to didn't do visual check.

Wondering if the Berk Hi-flow cat on the BRZ will pass? Anyone try yet?

[jaorocks1]

So let's say I gutted my stock header and front pipe... and run my e85 tune it will still pass? :O
