California Smog Check
 

Has anyone gotten smogged recently?

I heard stuff months back that the smog stations are now just checking your ECU (plugging in a obd2 scanner) for CEL and a visual inspection for OEM components.

Is there still an emissions test?

the smog program did change this year.

what we check is hook up our OBD II scanner to your car. it reads that all monitors are ready and no codes present (pending code OK). then we do a visual inspection to see every component is in place. If the car has any aftermarket parts we need to check the CARB # to make sure that built for that car and input the carb# into the system. if no label found on a aftermarket part we need to fail it.

Even if its a catback?

no anything after the secondary cat doesnt matter. you can have straight pipe it wont matter.

Also whatever I explained applies to 2000 and new cars only. All 1999 and older cars we still do the old way with the dyno and exhaust emissions

Does this mean my e85 tune won't pass? Lol I have to switch back huh... Damnit..

does e85 cause a CEL and a tune covers it? if yes then yes youll have to

Thanks for the info bud.

At least with the OFT E85 tune will not cause a CEL.

Reason I asked is because I plan to gut my stock headers, it sounds like I should pass SMOG okay so long that they don't do a sniffer test.

Wait, so catback exhausts are ok right?; considering everything else being OEM??

Catback is OK!

*Deep breath*....Thank you RevolutioN.
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.

what about catless headers, assuming it passes the visual? if there is a code relating to the cat that comes up, but a tune "hides" it as labeling it unready/not warmed up (or however a tune hides the cat CEL). I know some states only allow around 1 or 2 unready codes before they fail you or tell you to come back later. I am not sure if CA allows that.

Catless header will pass a sniffer test?

Good luck with that...

I assumed that it's just the visual and OBD2 scan. I thought the sniffer test/dyno was for the pre-2000 cars?

Entirely depends on where you live. Some counties in CA are completely exempt from smog testing... but people in other parts of the country just hate on CA as a whole.
