well as you know megan racing is using my header for development... they are making one for the cobalt SS and redlines. But he asked me a question today asking if the header for all 05- up ecotecs are the same! like HHR, 2.2 cobalt ion, G5 etc

now my question is only the flange the same or is the entire header the same? what is the part number for the 2.0 header vs a reg cobalt header?

thanks i need help asap!

 

Yes.The GMPP exhaust manifold fits both,so they "SHOULD" be the same.

 

awesome! i will have a new header on the market soon! they just wanted to see if they could use it for different platforms

 

That will only work on the 05's the 06's up have some weird air injection thingy for emissions

 

wtf u talkign about lol! air injection?

im talking about a header

 

Yeah there is some emmisions leech on the header
"Some interesting news has developed with regard to headers for the L61. It is important. In 2006, secondary air injection was added to the design of the car. This is an emission control system that routes fresh air into the exhaust manifold via a mounting provision on the manifold itself. Most, if not ALL aftermarket manifolds for this car DO NOT have this mounting provision, and at present is believed it WILL NOT work on the car. 2005 model cars should have no problems."

make sure theres enough room on the other models before selling them what if they bolt up but dont fit within the firewall and stuff like that!

 

well they are sending me 2 headers to test these are R&D units i will try and get them dynoed also or atleast one of them...

 

from my my talking to other HHR people yes your manifolds/gmpp manifolds/ headers will fit right up we have a member with a 2.2 who has taken manifolds off of cobalts and put the on his to make sure of this. He has assured me that they will fit on the 2.4L as well i own a 2.4L and will be buying a cobalt addiction header very soon if you need my conformation on the fit i can let you know with in the month.

 

awesome bro thanks alot! i cant wait to get my new test header(s)! (2 headers)

 

Please tell me 4-2-1 design! I really want one like that instead of the typical 4-1.

 

do you have an estimate on price? cause if so i'll wait for those verus the cobalt addication's let me know i am willing to put them on the HHR first, oh n from what else i found out we have more room btwn the header n firewall then the cobalts =)

 

probably 200 bucks i remember when people used to hate on megan racing blah blah blah but i did som review searching and people seem to love there products! plus the quality is great

 

painted or ceramic or stainless sorry for all the questions but i like options and my only one seems to be cobalt addication and for some reason they paint their stainless steel header not cool, at all
