i'm confused, everytime i searh for a header for my 2.2L, i come across pascetter brand .............. so i was looking to buy one. i emailed a guy from COBALT-ADDICTION about downpipes and the pacesetter which are offer on the website...... he said that COBALTS dont have a direct bolt on header yet, and that only the GMPP Honed Manifold would be the only one that fit perfect.

MY QUESTION IS, DOEZ THE PACESETTER BOLT ON WITH A PERFECT FIT OR NOT, AND WHY WOULD THEY SELL THEM 2 COBALT OWNERS IF THEY DONT FIT???????

 

no it does not bolt on

your stock downpipe needs to be cut just before the cat and the extension piece welded on...

and before anyone says anything, no it cannot be clamped on.

thats just the way the header is made, its slightly longer than the OEM manifold so it simply cannot bolt to the downpipe.

so basically if you wanna get the Pacesetter you may as well get a custom exhaust from the header back while you're at it.

 

Just to be clear if you get the GMPP it will be a PERFECT FIT correct????

 

The GMPP exhaust doesn't include a header I don't believe.

 

The GMPP manifold is not a true header. It is an extrude honed or ported Cast iron manifold. Same as the one on your car just bigger holes. That is all. Anyone with a decent dremel and a weekend free could do the same thing. But yes the GMPP unit is a DIRECT BOLT ON for the cobalts.

 

I have made a sticky thread in this very area listing for you all the manufacturers of headers for our car. There are a lot more then just pacesetting and GMPP.

The rest of the information is correct however. You will need to do some cutting and welding. However, any exhaust shop can do that for you quick and relatively cheap.

A "shorty" header is a direct bolt on. Hahn makes one that is in fact a direct bolt on for you.

 

other than the downpipe, does it directly bolt onto the engine? it doesnt have to be formed or anything right? thats all that matters to me.

 

oh it bolts up to the head just fine...as long as you don't have an 06

 

lol, i just bought an 06..lol. so...am i screwed ? are there no other 'cheap' headers that wont break something for the 06s ?

 

Ninja was a bit vague. A few of the 06 and later cars have air injection. If you have it, none of the current aftermarket headers will fit your car.

 

Simplest way is to look at the back of your engine and look where the exhaust manifold is. If theres a "gap" between the heat shield you don't have air injection. But seeing as you just bought an 06....you probly have it

 

if i have air injection and cant use aftermarket... i guess that eliminates the gm manifold right?

 

think this would work on an air injected manafold? i got a good amount of metal working experence...what would i make bigger?

 

/\ anyone?

 

you just make the ports a little bigger I believe

 

Actually, it's pretty involved. It required a different mounting flange. The manifold flange is normally flat. On the air injected models, the flange has recessed passages that allow fresh air to be injected into the head without mixing with the exhaust gas inside the manifold itself. Not a simple thing. It easier to see it then for me explain it. So here is what it looks like:

 

Poor 06's.

And all they wanted was a little Header!

 

Funny my 06 HHR doesn't have this. Wonder why? Oh and... anyone suggest a good header?
