i know this is for a cavalier but their the same motors...

think me and a friend could get this to fit on his 05 sedan?

No but go to www.turbotechracing.com and we have one that will fit the 2.2L cobalt. It is made for the cobalts

 

Smart Vendor... lol...

 

chances with that being such a earlier model, the heads could be slightly different

 

Looks like a nicely made header.

 

Ive actually been told a 4-2-1 would be better for a cobalt than a 4-1??? Is that true?

 

Depending on what you want in your car it is. I believe a 4-2-1 gives you more midrange torque than a 4-1. A 4-1 gives you more high RPM HP

 

Very true statement, however the ecotec has a very high amount of torque and off the line does very well. To me the ecotec needs more help on top end HP more than anything. Not many 4 cylinders stock will do what the ecotec does. This is why many people choose the 4-1 style on the cavaliers.

Also, the reason why the cavalier one doesnt fit is the chasis. It will bolt up, however the runners/downpipe is not made for the cobalt.

 

Agreed. Very nice header. I've seen more of Turbo Tech lately then most vendors. It's nice when they can answer questions even when they don't sell the product because they have knowledge and feedback on the situation.

 

so what fabrication issues have you guys run into? It states that is a direct bolt on so why does it say 'fabrication may be required?'

Any chance of the black painted header rusting after a period of time? I could care less if it looks pretty but I wouldn't want a header to lose the paint and eventually rust.

Also do these aftermarket headers have any effect on the factory cat? I know that with some cars if you don't go with an aftermarket cat after purchasing a header its toast within a short period of time.

 

Its direct bolt-on to the motor, but fabrication would be needed to connect it to the flange by the resonator. This header was made for the ecotec cavy's and sunfires. The downpipe would fit those cars easily, but the cobalt and IONs have a different exhaust setup than cavy's and sunfires.

 

The fabrication, is cutting the stock exhaust and welding on the new down pipe to it. That is all that is required on it. Just like the cavaliers were setup like.

It will not cause any issues with the cat converter.

As long as you dont have salts on your roads and you wash it here and there it will never rust away. However it is mild steel and not stainless steel. That is why many people choose the ceramic.

 

okay gotcha...and so if Im seeing the picture correctly...

you have the header in the picture, then after the header the cat bolts on, and then the last piece included with the header bolts to the cat and the other end has to be welded to the rest of the exhaust, correct?

If so, thats easy because I already have that flange (closest to resonator) cut off so all that would be needed would be to weld the piping together.

 

No, it is more simple than that. The header comes down with all 4 runnders to the collector. Then the collector has the ball joint on it that allows for flex in the engine without cracking the header. The other pipe that is included with the header connects to this ball joint. You cut your stock exhaust just before the cat converter. The header downpipe slides over the stock exhaust and you can either clamp or weld it there. You dont touch the cat, the install doesnt require you to do anything with the cat converter.
Does this make sence?

 

I can't really picture it in my head

Any installed pics on a cavalier that or Cobalt/Ion that I could take a look at?

 

i think i could probably get the header i posted to fit.... im going to put all brand new 2 1/4 or 2 1/2 pipe from the new header back, so i can fab that up.. its the same head... so i dont see why it wouldnt bolt up, my only thought is the firewall, might have to bang out the firewall a little?

we just plan to put that 2.2 supercharger kit from gm on his cobalt and spray it with a 50 shot at the track and see how it does

 

The one for the 2.2 ecotec should fit the 2.4 ecotec. Just make sure you get the one for the cobalt and not the cavalier.

 

sorry for my Ignorance but what would a header do to help out a car ? I am looking at getting a Cat-back exhaust would this make that better or ??/

Yaldain

 

It allows exhaust gasses to exit the engine a little quicker, letting it exhale a little quicker without a buttload of back pressure, and it'll free up some ponies... You have to be careful though if you add an exhaust not to get the piping too big, if you lose too much back pressure, you can lose power.
