Does anybody make anything for our application yet, or is it the same as the coblats ? if so, they have headers out for them already, so does this mean it'll fit the hhr as well ?

dont think so, you know anything infront of the converter voids the warranty right

And wouldn't it just be a single header rather than two seeing as how it is an inline four cylinder? :confused:

I think i remember that pro-motion was working on one.

well, you know what i meant, and to the voiding of the warranty, like a header will hurt my motor. I just curious to see if there was anything available and i guess not.

The Ecotec 2.2 litre is same engine in the J-Body (Cobalt/Cavalier). The only problem I could see the HHR would have is the exhaust manifold may have different ports than the J-Body.

It has the same ports because the head of a 2003-2005 J-body is the same, and a 2.2 cobalt head is also the same as a 2.2 HHR head. The problem would be if it cleared the firewall, and the steering rack.

GM performance makes a header for the cobalt...I figure if you adapt that one, you're golden.

The headers for the HHR and Cobalt are the same. A friend here in Tucson has a Cobalt with the 2.2 like I have and we got bored one weekend and test fitted his header to my HHR and it fit! Header was made by SCDyne. If you check JonyyB's other forum www.cobaltss.net they have a 2.4L Performance forum and have all kinds of performance stuff in there. You might try it out! Hope this helps!

Lots of goodie parts on that forum.

Yea, im looking at a scdyne header as well, only bad thing is the website claims 499.99 for it which is pretty steep, but oh well, ill be the first to say i got one on there for good, lawl.

FYI: They had a few on ebay last week with a buy-it-now at 1/2 that price. Also according to an email I got the price online is for 304 stainless steel.
They have had problems with manufacturing quality in the past so be aware.

theres a lot out there for our cars now.

ok I am posting a picture of the header that is in the making's I still have to test it and see if there is any thing that needs to change.

If your putting that much time and effort into it, why not make equal length runners?

Exaaaaactly! I was hoping someone else would notice. The #1 & 2 cylinder runners are way to short (*that is the two end runners for newbies). Perhaps your header guy should read a few books on exhaust scavenging.

Not intending to "Bash" - but why go to the trouble of making something if it doesn't work right? :confused: A 4-cylinder engine needs proper scavenging more than a V8 does.

ok once again it's a prototype I am working with companies to make it work. I guess my header is kinda like the triple lake pipes just needs to be redone or not used at all...................not trying to bash

No it has good workmanship, just a header with equal length runner will out perform the one you are having made, but the one your having made will work better than the stock manifold.
