Impressions after header install...
LIKE OMG!
OK so I had my Pacesetter header installed today. I am VERY impressed with the results. I mean, I havent reset my computer yet, but I drove to work and was in 2nd gear doing 40 and punch it, when I get to about 6000 RPM my tires come off the ground.... Did I mention is FREAKING DRY OUT! I have never had that happen before. To be honest it very slight, but its like 1 tire comes off and starts to slip. Its freaking sick!
The dood I took it to, did all custom ****. You can see it in the pics below. He added a new flex pipe, and shortened the downpipe. It looks really professional, especially when looking at it while under the lift.
Now I do seem to get more knock then I did before. Like before the header install I was almost 0 knock at all times, even at 7 K. Now I havent checked it recently, but that was like 2 months ago. Now w/ the header and me checking it, I see 1-2 degrees of knock up high in the RPM's. I dont know if this is because of the header or of this can be because my copper BRK7e's might need replacing? I mean I also havent reset my Computer yet, so that might have something to do with it.
Now when I put my new spark plugs in tomorrow should I gap em at .40 or .35? Which would be better for less knock/performance?
Anyway, yea the header ownz! I cant wait till I race my brother tonight. We where dead even before the header so it will be a good judge of performance as far as what I may have gained.
Also downshifting into 3rd gear at 15 MPH seems like much more power there then before, and more power in just normal driving, not just WOT.

he charged me 75 bucks for the install. It was a local meinke but the dood their knows me and my bro by name and does everything under the table. he did our exausts, and high flow cats etc. He came in on his day off and did this for me.
At first it was making a weird rattle like noise, and he kept going back and checking it thinking something was wrong. Finally he said everything was right and he thought maybe the gasket was bad or something. Well I started the car up again, and the noise was there, he couldnt feel any leaks near the header so we just let it sit and after a minute or so it went away. I have stopped and started my car since and it hasnt reoccured. I havent let it fully kool down, so I will update tonight if its still an issue. He said I could bring it back if problem comes back, he thought it might just need a small layer of carbon or something.

Great news . Nice to hear someone happy with one of the lower priced headers . Pacesetter made really good long tubes for the F-bodies too , so its cool to hear that continued over into the Cobalt .

I could tell you the gains on mine, I installed my header the same time I installed my 2.6" pulley and 3" exhaust, so I was terrified of my car for over a week before I got the ***** to see how much fast it really was!

A header is the best way IMO to gain bolt on performance. Used to see loads of BBC and BBF towing rigs that had nothign more than headers adn K&N filters, and they guys said the only real gain was the the headers. TUning the runner leingths helsp an engine tremendously. Take for example a SR20DET out of the Silvia/240. Going from the stock exhaust manifold to a tuned leingth turbo header a guy I know gained almost 50WHP! But this of course was with a T3/T4 and he was boosting pretty good. The biggest limiting factor in most stock vehicles now is the exhaust mani because it has to clear a tight engine bay, and give good clearance, plus it has to be short so the Cats can warm up faster. A good tuned leingth header however throws emission out the window for performance, so you get a pretty damn solid gain in any car.

No rattle after starting my car up in <30 degree weather after sitting for 9 hours.
I did pull a check engine light but I cleared it before I checked it by accident Meant to choose view DCT codes, but hit clear instead.
I am supose to reset my CPU after a header install right? I still havent, and I think thats the cause of my probs. I am going to do it tomorrow morning, but I want to put my new sparkplugs in too and reset it after that too.
