Next time I have emissions testing, I'll let you know. I have a Borla cat-back system, a CAI, and a supercharger. If any of that stuff causes me to fail, I'll come back here and ***** about it.

I say bolt on whatever you want. As long as the stock ECU is used, you should be fine. If you go beyond that with some sort of stand-alone or cracked ECU, best to do some research then about codes, sensors, etc. regarding your new tune. If you can throw the old ECU back in for testing, you should be good.

Also remember if you clear any codes, or swap out an ECU, do not go directly to the testing facility. They will know and the car will fail. You have to be able to drive it for a week or so with no codes. Put at least 100 miles on it and go back for testing. Ask me how I know!

The answer is... none. None more black.

I am a former SoCal resident and I know about the CA emissions crap. I too was worried about modding, but......

I have a 5.7 with a 392 cam, shorty headers, CAT back exhaust, CAI and a custom tune. I got my dreaded notice for testing this year and had to take it in March.

Well no problem, all they did was plug into the OBD port and print out my PASS certificate.

If the check engine light is on and you are throwing codes then automatic fail.

Happy modding!

If you reset your PCM and don't drive the car a couple of days to get data on it - fail
If your service engine soon light is on - fail
If your service engine soon light is off but you have a stored or pending PCM code - fail

No visual inspections. I knew someone several years back who ran an O2 cheater (home built using a 555 IC) jumpered to the battery in plain sight under the hood and they passed twice. Lived in IL all my life and only failed once because I reset the PCM the day before (replaced faulty TPS) on an infiniti. I am running corsa extreme cat back with a maggie and am very confident the car will pass next year. Also have a friend with a supercharged bimmer running O2 cheaters downstream and he passed 2 months ago. Back when they use to run the cars on rollers and monitored, exhaust, checked gas cap, did visual was a little more difficult to pass. Back when I was in college (90's) I had a fiero and the knuckle head placed the front tires on the rollers even though it was rear wheel drive. In short, you will be fine.

It's the increase in gas tax, the sweet drink tax, increase in income tax, property tax, tolls that you should worry about...well that and the state is financially broke.
