Sai Or no Sai looking at headers and the cobaltpp website has a custom header and it says it doesnt support the sai. I was told I dont have on but on their site they insist all 2.2s and 2.4 07s have them yet someone onhere said nay. Need somemore anwsers

 

I dont think that any of the 2.4 had SAI... the simplest way to find out, is look under the hood and see if there is an extra tube going from the airbox to the header

like this:

 

ok THats what I thought cuz I did acualty check just wasnt sure

 

its ok, i only know b/c i just recently researched my 2.4 b/c i bought a header/dp...

What header are you looking at? i got the ZZ Performance midlength header/dp combo

 

was looking a cobalt vibrant 421 stainless steal header at cpp but Not real seriouse about that one. Hows ur combo working, I seen that one and now that Im understanding how this stuff works alot better sounds like a better buy

 

i haven't put it on yet, b/c i ordered a Catback exhaust also, ill probably put it on this weekend...

But ill let you know how i like it

 

definatly a good buy their/ I know its not legal but is it better to have no cat or somthing???

 

I went with the cat... I even made a thread about it:

https://www.cobaltss.net/forums/zz-performance-99/cat-vs-catless-74012/

basically the even more increased noise outweighed the <2hp that i would gain from going catless.

Just remember if you do get a cat to drive ~300miles without going WOT

 

wide open throttle means what exactly

 

Flooring it

 

bingo... basically for the first ~300miles drive like a normal person... Dont run out the gears, or mash on the gas

 

Why, I can't NOT do that, it's not in my nature to drive like a normal human being.

 

cats work on a few key things, the bit to remember is that the reaction in them renews itself.


in other words, if you crud it up too fast, you'll make it less efficient and it will fail early.

i'd say, if you install a new one, let the car run for at LEAST 10 minutes at idle to warm up, the drive it (under 3000rpm) for about a half hour. then let it cool all the way before driving again.

after it cools is a great time to re-torque the bolts.
