i have an 06 2.2 and bought a 2.0 header..dont no wut year the 2.0 header is.. just texted the kid i bought it off.. i brought it to the mechanics and he said the header fit into place but it was missing an erg sensor( it regulates the pressure in the exhaust manifold) so he said he couldnt do it bc my care would throw a CEL and run shitty.. anyone ever heard of this.. and im gonna try to sell the 2.0 header.. the clear image for the 2.2's. does that come with that erg sensor? just asking before i buy it

 

SAI intake........the only reason i hate my 2.2...............u can get it tuned out

 

Yep it sounds like you have the SAI (secondary Air Injection System). Your engine's exhaust manifold looks like a header and is welded steel -- not cast iron -- and it has a valve that sits on top of it. No companys make a header to replace it.

 

just install it and you can get the CEL tuned out it wont hurt anything..........just search SAI and ull find all your answers

 

pacesetter was gonna make a header for it a while back but no one would give up their mani for the R&D of it. aaron with ttr tried for a while to get someone to give one up but no one was willin..

 

i thought my SAI was attached to my intake.. i disconnected an extra tube coming from my intake when i put my CAI on then it was just an open hose so i put a breather on it.. my mechanic said it was an erg.. he was very specific about it.

and how do i get the CEL tuned out

 

really.......i wouldn't mind taking a road trip to have them do it wit my 2.2...........no college for january

its the SAI dude...........and u can get a trifecta tune

 

I think your mechanic is saying "EGR" -- the Cobalt does not have an EGR system (Exhaust Gas Recirculation). Tell your mechanic it is an SAI system -- and then tell him it is the same as the old GM "AIR" system (Air Injection Reactor) that GM started using in 1966. The difference is the AIR system used a belt driven pump, while the SAI uses an electric pump. Fresh, filtered air is injected into the exhaust manifold to reduce hydrocarbons -- part of the emissions system.

 

yea give me a few minutes and i'll try to find the thread bout it.

ok this was the thread aaron with TTR started bout gettin a header made for the SAI.

yea but isnt a tune a pretty penny for just a header.. i mean i do have a CAI, ARK catback and if i bought a header i would prob do the clear image header dp combo..So with a CAI, catback, header & dp ..t hen would it be worth a tune? just wondering bc a tune for just a header seems silly.. unless the tune would be less bc its just a header. not rele schooled in the dept of tunes

 

should cost 200 bucks for a tune specific to ur mods.......it will be worth it.....or u can do your other mods and wait for the header and then order a tune....

 

oh yea it'd be worth it. a tune will bring the car to life man. it'll cost you 400 to get the tune but you'll get 200 back after you send the tuner back to vince.

 

...or if your mechanic has the know-how he can disable the SAI. SAI can be disabled with the same equipment the dealer uses when they put 16" wheels on a 15" wheel-equipped Cobalt LS. Once it is disabled you can remove all the SAI sh-tuff and put your header on it. HOWEVER...since it is part of the emissions system if your state requires it you are SOL.

 

only on cold starts......the system only engages for like 30 seconds anyway its so dumb and a fricking headache..........

 

There are five states that have the requirements...California as usual led the charge, New York is another, and I can't remember the other three without looking them up.

It is possible the 09 2.2 doesn't have SAI due to the VVT...anybody with an 09 2.2 have SAI?

 

no idea im in NY and i know for a fact that as long as its not tested off of a cold start it will pass

 

Then if he can get his mechanic to do this...problem solved!

 

so is there a consensus to sell the 2.0 header and get a clear image header and dp then tune?

i was just looking at clear image and they cost way too much to just spend on a header in the position im in.. maybe i will stick with the 2.0 header.. so if it is installed and it throws a CEL meaning the SAI is not connected ..will it *** up the exhaust manifold or engine?.. and to get one more thing straight, its not an ERG definitely, its the SAI.. my 2.2 dosent have a ERG right. its the SAI.. 100%? just want to double and triple check so when i go back to my mechanic i can fully and clearly explain to him wut the deal is.. bc many of u may know.. mechanics dont like fukin around with **** like that. u know. if its not suppose to be there they dont wanna take the chance blah blah blah.... thnks for the help so far guys.. really appreciate it

 

no erg its the SAI........trust me i went through this a few months ago when i discovered this problem

 

howd u handle it? and if thats the SAI wut was that extra long black tube the was connected to my stock airbox that sux air in for like 30 secs everytime i start my car? no i just have a breather on it. is that the front part of the SAI which runs back into the exhaust manifold?
sorry for being annoying bout this.. i just dont want to take the train back all the way to the mechanic and tell him everything that you guys have told me, then have him say something and be like, oo wait umm.. and then havta come back here and ask more questions

 

yes its the front part.............i didnt remove mine.......orngbalt......he has it done send him a pm
and its all good man i dont mind sharing my knowledge

 

orngbalt? thats his whole name...ite man..appreciate the info. lemme see wut he has to say

 

The tube that attaches to the filter box is for clean filtered air -- goes to the electric pump (between engine and radiator) then another tube runs to the checkvalve on top of the exhaust manifold. Since you put a filter on the end it is still working properly.

 

so if i tell my mechanic to just go ahead and put the 2.0 header without connecting the SAI.. it wont harm my engine or raise my exhaust mani temps correct? my emissions might just be a lil dirtier for lack of better words? it will throw a CEL but thats it.. wont harm my car or the way it runs?
