Question Cobb Cams in CA? (smog)

I really want to re-cam my car, but I haven't heard if anyone has gotten theirs sniffed out yet. Is there any reason to think the car wouldn't pass a emissions test?

I'm curious too. I heard it idles like stock, so that is good. Anybody have any readinds on the sniffer? I doubt it though...anybody with these cams probably doesn't have to get their car smogged for a while.

Email cobb and ask. I have the feeling they could care less about Cal specs. That would hinder any performance for the other 49 states they'd sell their product to. I know the cams aren't carb approved. I asked when I thought about gettin them.

I have a set of B Spec cams in my car right now (mild turbo regrind) and I can't see how the smog people would be able to tell unless they pull the valve covers off and measure the lift, duration and overlap.

Unless you go for a super aggressive NA profile, your smog shouldn't be any problem, as all they test is idle and 2500 RPM no load, since there are no AWD smog dynos in Cali.

yeah dude, speaking of awd smog dynos. i went to have my car smogged the other day and the guy was yelling at me for watching what he was doing, but if i hadn't watched him, he would have put my car on the dyno and driven it right into the wall. goddamn people who don't read manuals.

That's exactly what the guy at Cobb said...you could only tell if they had a stock cam, and held them side by side...other than that, the only thing that would give you away was if you didn't pass the sniffer.

If your car idles rough, the could tell it was "cammed" but they might not give a $hit.

So Spiral, did you pass the sniffer? How come you had to get it smogged?

is it that you don't want them to be able to tell if you changed cams, or is it that you are concerned about passing your emissions test? it depends on the lift/duration/overlap compared to stock. You did say you wanted to get mild ones right? I would
nt worry about passing. Unfortunately you live in CA. so it is illegal to drive with them on the street right? it's your call.

Oh go for it. but don't forget that you exchange your stock cams as a "core" right? Something to think about before you jump in.

Anything that you do to your engine that could possibly affect emissions must have a CARB EO # to be legal. Heads, cams, headers, intake, etc etc - they are very anal about it.

I recently installed Cobb "Street" cams in my '97 Legacy and I think they are quite noticeable at idle. They might not be noticeable to Joe Emissions-checker who doesn't drive the car every day, but I can definitely feel the car hunting a bit at idle. I don't have to get my emissions checked again for about a year and a half, so I won't know for a while if they're OK or not. (BTW, CT emission standards are as strict as CA (although thankfully we don't have anything like the CARB to worry about), and every test station has a set of AWD rollers for SUVs, Quattros, Subies, etc).

So you bought this used? The person selling it is actually supposed to get it smogged, before they sell you the car. They can't sell you the car as an "operating vehicle" if it doesn't pass smog. That's why they have to get the certificate before they sell it.

Patrick is right. If you mod your car, keep all the stock parts, because you may pass the sniffer, but if they look under your hood and see a ganz or a cobb intake, you'll fail visual. My brother said I might get away with my borla header and catback..but at the least, I'll switch the catback.

IIRC, the Borlas are legal, and anything after the cat is just an issue of noise anyway. I'm just worried about passing emissions - Show me a smog tech. in San Diego who can tell the difference in how a EJ25 idles, and I'll show you a guy I probably already know on a first name basis. Besides, if you pass, you pass. I doubt they could do anything about it, even if it occurred to them. So Spiral - you have cams and passed? If so, I'm in there.

What's the b-spec URL?

The Borla header which I have (gen 3) doesn't have a carb #. The older ones, did...i think. Or at least the 1st gen did. You are right about the catback though...but I remember reading on the slip that came with the header "50 state legal....for offroad use in California"...and we all know what that means!

But I agree...if you pass the sniffer with Cams, then all should be OK. I have just heard CARB horror stories. I posted a while ago in BAIC about passing the sniffer with cams...and the only responses I got was to basically not worry.

Not to hop on the American V8 Bandwagon again, BUT, my '91 CamaroZ28 has the following aftermarket items on it. Edelbrock Cylinder heads, Edelbrock Big Mouth Intake, Roller Rockers, Rods, ZZ9 Camshaft, and Arizona Speed and Marine Intake Runners. It also has a laptop programmed Performance Chip in it.

All those mods and it still passes smog every two years with flying colors. .17 of the .93 microcarbons (or some technical term) is what it scored last time. BTW, they're all CARB certified parts. If they weren't, would it change the outcome of the test?

I think you should be fine with just cams, Chris.

In theory, you wouldn't pass due to the non carb certified parts, despite passing the sniffer

Just because it has a carb number, doesn't mean it will pass or fail the sniffer. A carb # only means it's OK to use, it does not mean you can skip the sniff test. Likely however, if you just have one or two carb certified parts you will pass the sniffer. But add a $hitload of parts, and even the carb# won't save you if you don't pass the sniffer.


That's the way CARB works. You can have the cleanest car in the world, and if you have one aftermarket part (that could possibly effect emissions) without a carb #, you're screwed. You have to pass two stages, visual and the sniffer.

So, yes it would change your outcome. Although it may not change your tail pipe readings, you would fail visual
