Legal California Modifications?

yaoxiao4

Hello,

I recently got my Z (Black 2013 Touring Sport) and I was wondering what are some California legal modifications I can make?

So far I have purchased a Stillen Gen 3 CAI and a fast intentions CBE, and I'm aware that any changes to the cats/headers are illegal here. In the future (maybe far) I might think about a Stillen SC since that's CARB legal.

Any ideas?

Thanks!

Your exhaust isn't legal

I think even the CAÍ isn't legal either. Sucks we have all these restrictions unlike the rest of the country but at the same time it's good thing for your health. Just go to TJ across the border and you'll be glad California has so many emission restrictions. That place smells nasty of burnt gasoline everywhere you go

Stillen Gen 3 is CARB legal, it has an EO #

I have the Stillen CAI & FI CBE, no problem passing smog test.
The Stillen CAI is indeed CARB legal

How'd you get by on the FI Exhaust?

Did you have an understanding with the test place?

I want to grab one and slap on the FI HFC i have lying around but am waiting till next year when I smog test, then i don't have to swap for a while

You are wrong. Nothing behind the catalytic converter matters in terms of emissions. Sound maybe, but not emissions...

You are wrong also. The Gen III from Stillen is CARB approved.

Thanks, I was getting a little worried because some places had said that CBE is legal because it doesn't change the cats themselves. I have the 18" resonated so maybe that'll help with the sound

yaoxiao4

well the HFC definitely isn't going to be legal, but I don't think catback is illegal since it doesn't change emissions from my understanding, and it's below the decibel limit

The HFC's would be the problem, not the CBE

You could find a place that would let you slide on the cats but, that's on you.

I have my oem cats still.

I've gotten by once with an aftermarket cat-back, but failed another time on visual exam, thats why i asked.

guess you just gotta find a cooler place

Properly tuned i am certain that the Gen 3, HFC, and TDX would pass a sniffer, its just getting an overly strict tester that i'm worried about

On Cat-Back Exh... I saw somewhere that if stock has a crossover pipe, your aftermarket needs one too. I don't think there is a distinction between X and H configuration. Noise restrictions too but it you have a stock cat you will probably never get "hassled by the man" for it.

CAI... I think any mods are OK in front of the MAF sensor.

No alternate cats where listed last time I checked.
