Well i got the header on friday! I installed it on sat it took me probaly close too two hours to finish everything. It was an nice looking header i didnt have any fitment issues excpet one nut was really close to one of the tubes, so i had to use an open end wrench instead of an socket but it wasnt no big deal. I dont have any exhaust leaks and it sounds preatty good it kept the sound level about the same but made it deeper and it sounds bad ass now, i have the catback magnaflow and it sounds really good now with the header. As far as performance goes it was an alright increase nothing amazing but defintly worth buying. When i have the clutch engaged and go to rev it up it revs much faster. Between the pulley intake and header my car revs really fast now. And before the header it didnt have all that much power untill the vvt kicked in at 4k but now alot of that lag before 4k is gone and it pulls alot harder after 4k also. Im defintly happy with it even though it took 3 weeks to get here. Sorry i didnt take any pic before the install but im gonna take some pics tommorow of it on the car.

 

awesome news! can you show any videos of your car revving

 

well... apparently here's the answer to the "will headers fit" question.

 

Yeah, right after I made my post I checked out SCdyne's site and noticed that they list they header as working with with the 2.0, 2.2 and 2.4

That's a sexy looking header Jas!

 

what'd she cost you and where'd you order from?

 

i was thinking about getting the scdyne header but everyone complained about their headers not fitting correctly. I have the gmpp manifold in my room waiting to be installed but havent got the time, id like to see some dyno's between the two headers though. Who knows maybe ill sell my gmpp manifold and wait for something else.

 

It cost 420 shipped and i ordered it straight from scdyne.

 

not bad. I'm trying to decide on this or the weapon r. The fact that this bolts up to the stock exhaust is nice and that it doesn't eliminate the cat.

 

good job man now all you gotta do is go down to some tracks and get some times back to us.

 

The day after i installed it i ran it in the 1/8 and my fastest time was an 9.61. im gonna be ordering my ecu tune some time this week or next and im hoping for low .5's or high .4's my tires are really sticky so they hook up preatty nice and i can launch it half way decent without to much wheel hop.

 

where did you get the pulley from

 

I saw the pulley at http://www.rsmracing.com/cobalt.htm

 

you can also get it from www.racingsolutions.com But it took them an while for it to ship it to me and jerryg is having the same problem???

 

what companies make a header for a 2005 2.2 Cobalt Ls coupe??? I've only heard of Pacesetter and Scdyne...which would u recommend???
