there is no header that meets california emission standards for our cars....at least not yet

we all wished it was that easy, but we have 16 pages of posts trying to figure out a way around it.

Do you know when they're suppose to come out with california legal ones?

Halfcent

"They" won't. Plain and simple. Carb requirements just won't allow it. The best thing you can do is the flash tune to remove the system completely, but that is still not legal in California. It would just look totally normal to any cop that might inspect your car.

My 08 Ls seems to have it.

K&N is the only intake that would work, right?

avenger09123

all the intakes will work, you'll just have to hang the hose on a bolt, get a filter for it, or remove the hose, how you do it is up to you, it won't give you a check engine light.

Thank you very much.

CobaltLs_14

Any word on a performance Header for the cobalt ls thats CA legal?

Sarbae

No aftermarket exhaust modification is CARB legal, unless you're repairing a broken system.

CobaltLs_14

Nothing yet... do you know where i can go to request one or have a custom one made?

Halfcent

Please try to stay on topic. This thread is concerning SAI. If you want a list of aftermarket headers, go to this thread:

hey halfcent, normally I'm inclined to agree with you, however, there really isn't much in the threads about headers relative to SAI. I believe Cobalt14 has a point in asking about them here, as pretty much anyone who overcomes this problem would not post in a header section because those of us with SAI are so few and far between, the posting in the old thread or in a new thread would be pushed down in no time, and very quickly forgotten about.

Halfcent

Okay, but I assure you the question being asked here was already answered in the body of this thread. No company is going to make an SAI capable header for this car. There isn't enough market for it. As for making your own, that was also covered. You would have to get an SAI mounting flange, and then weld whatever kind of plumbing you wanted to it. The best idea was to buy whatever header you wanted, cut off it's flange, and weld it to the stock flange. But because of the large amount of work involved with minimum gain, it wasn't feasible. If you are going to that much effort, then just get the reflash that removed the system completely.

Is it true that pacesetter makes a carb legal header for the 2.2l?

Part # 72-1272 or 72C1272?

Halfcent

According to Pacesetters own web site, the two headers they make are not listed as "50 State Legal". So I would have to say no.

Sarbae

Okay, for like the 20 bajillionth time, carb says it's illegal to modify your exhaust sytem. Period.

shawn672

GMPP Exhaust = modification but it's carb legal...

i think you meant it's illegal to use any 3rd party exhaust components

Nato09

which exhaust sounds better.. magnaflow's, borla's, dc sport's, or corsa's?

avenger09123

none of them, go ask this in a general forum

irishredheadpa

I am highly confused, i have a 2006 ss/sc and i want to put a full exhaust system for my car, how do i know if i have a sai or not?

avenger09123

You don't. NO SS/SC's have it in them, go for it

Halfcent

Read post number 1. Then stop reading.

j.ho7

some of the the SS have 2.2L in them...

read the other posts and it's explained

Halfcent

Not true. Not a single SS model has the 2.2L L61 engine.

avenger09123

Halfcent's right. No LSJ 2.0L or LNF 2.4L has , will, or ever will have the SAI system. SAI only comes on L61 2.2L motors, and even then, not on all of them, it seems they were made and spread out throughout delivery.

----On a separate note------

I was looking at the electrical diagram for the SAI system....I'll post a picture of it tomorrow.....but it looks like it only has 5 total connections to the PCM
------
Connections 1 and 2 are the relays that allow the system to start and stop by providing +/- connections
------
Connection 3 is a 5 volt reference from the solenoid

Connection 4 is a Low reference signal
------
Connection 5 is an Air Solenoid Pressure Signal

If I'm right (and I am), the only thing that distinguishes between throwing a code and not is the combination between the air solenoid receiving the signal and putting out a signal for the 5volts.

Ok so for removing the SAI hardware - it makes for an interesting modification.

Tricking the system into thinking the air pump is there is easily done - you just remove the pump and connect the wire that powered it to a ground, and it thinks its running the pump.
However removing the solenoid is a big issue. You can remove it the same way, just grounding the power wire. Here's where we run into a problem. The PCM is going to supply a signal to the Solenoid and its either going to return a 5 volt reference or a low voltage reference. If you remove the solenoid completely, the PCM can't get either the 5 volt or the low voltage, it will throw a code for a malfunctioning air solenoid.

To be absolutely and completely honest with everyone that reads this, it most definitely looks possible to remove the air pump, and the solenoid hardware in our cars.
Grounding the air pump power allows the "air pump" to run, grounding the solenoid valve, allows the "solenoid" to work when requested by the PCM. It looks like if you jump the connection between the PCM sending the signal and 5volt reference------or just make sure its a 5 volt reference signal that makes it back to the pcm--- you shouldn't throw a code at all.....interesting...

This is the most promising thing I've seen so far. I'll give it a go this weekend if it works - I'll tell everyone the parts they can go buy from checkers and radio shack and how to solder the right connections to do this to their cars. The way I see it, checkers has connectors you can buy to fit OEM chevy and ford connections...so that way you can reconnect the system if some smarty pants DMV inspector decides to give you trouble. Remember though, doing this is illegal and you do it of your own free will and I will not be responsible for anything that happens in regards to the punishments incurred if your caught

Very nice, Blake!!

Now...what if the pressure signal isn't a 5/0 volt reference and it's monitored by a change in resisitance? You'll basically be playing with a bunch of different resistor values until one fools the PCM...
