http://www.zzperformance.com/cobalt_...=545&catid=155 I am so confused on what to order. I have an 08 Ls Auto/SAI I need the extra o2 bung and plug right? What do I do for the model and errr this is so confusing. is it just easier to get a shorty header and attach a lsj dp? I feel like the ZZP combo would fir nice and snug.

 

I have an 07 LS Auto non-SAI, but when I order mine, here are the options I will order:

Auto
1.5 high temp paint
magnaflow cat
mild steel dp
2.5 dp bolt-in
none selected or bung and plug (not sure what I'll do yet)
keep my dp

My plans for my car are Injen intake, midlength header/dp, lsj cat-back and possibly a tune. I won't be doing the 2.4 manifold, cams (can't anyway unless I get the ones from Bikeboyben14), or any other power adders. That is unless I go S/C in a few years...I'm going to try to save that money towards a Sky RL instead though.

 

i went with 1.75 primaries (stick to 1.5 if you're staying NA), ceramic coated, steel 2.5" DP, added cat, extra o2 sensor

 

yeah well i wanna go stainless steel so errr iam gonna try and hope i order the right one

 

No thread hijack, but can this bolt up to the stock manifold?

so u have SAI and u getting a header with out SAI??

 

x2

There is no header made to accommodate the SAI, unless you're getting it removed. That's why I asked if that downpipe would bolt up to the stock manifold cause I have the SAI too.

 

yes extra o2 sensor

 

well if i get the extra o2 sensor do i have to get rid of the sai? and I can just get rid of sai anyway with a tune.

 

you know...i have SAI and ive got the ingen intake so my SAI isnt even connected... but yes i do have the stock header/dp but i dont think youll be having any problems by just not hooking that gay **** up... others may feel differently but thats my imput/opinion on it

 

Wait how do I tell if I have SAI or not? I have 05 NA.

Im ordering the same thing so what do I have to do?

 

No 05 ever had SAI so order away and enjoy.

 

you dont have a SAI, only newer models have it

 

if you disconnect the SAI pump and leave it hanging (IE not connected to an exhgaust manifold) then it will throw a CEL. If you remove it compleely, you will have a different CEL. You need to tune it if you dont want CELs. I speak from experience
SAI started in '06.. so not just the newer cobalts

 

so should the tune include getting rid of both lights cause i just want to leave it hanging

 

ok, here's the deal. if you have sai, you will have to remove the system to install your header. it's not hard to remove, you can pretty much look and see where the system is bolted in. me and orngbalt were one of the first to take it off, with no writeups or anything, and it was cake.

you will get a cel, unless you get the tune. but it will not cause any driveability issues, will just have a cel.

 

so their is no way of installing header then just zip tieing the hose?

 

you can do that. but again, you'll have a CEL

 

just get over the fact that GM fucked us hard with SAI. i've come to accept it.

 

or just remove it like me...

 

did know that, thought they started 07+ learn sumthin new every day lol

 

i learned that I should of saved and bought a SS

who doesnt wanna **** hard...thank you gm

 

SAI is no big deal it just slightly improves your emissions, it took me 5 minutes to remove when i was putting my supercharger in, just have vince tune it out (if/when you get your 2.2 tuned) and you won't have to worry about it ever again, unless you fail your emissions test haha.

 

y? some1 will make a header for it. **** my 4.3L blazer has it and JBA makes headers for it. my 3.8L firebird has it and they make headers for it. clear image said if they could get a SAI car they would try to make 1

 

Well it's been in the Cobalt since 2006 and no one has took a swing yet. With Cobalt production ending next year I doubt they ever will.
