more than likely most dealers will not know the difference in the 2.2 and 2.4 mani's they look alot alike except for the runners are a lil bit bigger. so unless they happen to really know somethin bout the balts then they will not ever know the diff in it. as far as voidin the warranty they cant untill they can prove that a mod you did actually caused a problem you bring the car in for. all they can do if the happen to know its not the mani that came on it is flag your warranty so they know you have somethin different on the car than what was suppose to be there. no for your exhaust question. 2.5 is the biggest you'll want to run on your car unless you go f/i cuz the motor wont ever put out enough power n/a to support usin 3in or larger exhaust.

 

Ok perfect man thanks alot youve helped me out alot in deciding what to do,Im def going to do this a few parts at a time and store them until its complete.Im just not sure what to do about the CEL's that are going to occur.

 

reading > me

 

im no expert, but from what ive read. save your money. and buy the vibrant header, d.p. combo. get whatever intake, exhaust you want. and enjoy your cobalt.

 

What does it matter? It is still a question of SAI or no, the 06.5 and newer with California emissions standards came with it but that was it and not every state is cali emissions.

 

Well im in florida and i dont have that extra pipe so i dont think i have sai

 

Yep,

If you have it, you will see an extra tube coming right out of the airbox.

I guess I'm going to have to do everything except the header for the exhaust.

 

its an 07 thou and should have sai (or AIR as maven said it is really called lol) on it. just look comin from the factory intake and the factory exhaust mani. it will be black plastic pipin. all you will need to do is get a tune to have it turned off.

 

it's not that easy to "have it turned off" .. but he says he doesn't have SAI anyway so w/e.

btw florida emissions requirements are almost as bad as CARB aren't they?

 

we dont even have emission laws unless u get stopped by a cop having a bad day lol

 

Refer to my previous post. SAI is not required on the car unless your state adapted CA Emissions. Ask Facelesskhaos, he has an 07 with no SAI.
