get an exhuast while your at it too lol. HP Tuners with the 2.0 injector swap is pretty popular too. you wont need the monitoring guages or the dash hawk imo, put that money into suspension such as lowering springs, rear sway bar, strut bar, and maybe a torque dampener to help get more of the power in your car to the ground
thats just my 2 cents, hope it helped

Well, with a hot air intake and a 3" exhaust on a stock 2.4....

That'll put you in the 16s for sure!!!
Seriously, the first thing you need to get is a clue. Don't take that wrong, please. You've been reading too many ads or reading posts or taking advice from people who just don't know. Find someone with experience about modding and tuning and learn as much as you can first. Otherwise you'll be pissin' away your money on stuff that just won't work right on your car.

The real problem you're going to have while trying to learn is how to tell the real deal info from the internet or local "experts".
Find a reputable shop in your area. Go see 'em, get to know them and ask questions. Go to the track and do the same with the people who are winning.
As for your list.... Just an opinion from a 60 y.o. engineer who's raced since he was 9....
Intake: Don't really expect much here, other than looks and sound. I've looked at 2.4 Cobalt data logs and the intake draws air from outside the engine compartment, which is cooler and denser than underhood air (denser air makes more HP). The manifold pressure remains steady through a pull, meaning that the stock intake is not restrictive. If you want the looks and sound, make sure that the air source is NOT hot underhood air.
The header won't gain that much either. The stock manifold is pretty good flowing, especially compared to stuff years ago.
For the rest of the exhaust, 2.25 will be good for a relatively stock engine. If you take it further N/A, 2.5 may work. It's not about size, but flow velocity, gas inertia, scavenging, etc. Get away from the concept that "bigger is better". Be environmentally responsible; forget the catless DP. A good high flow will make very little difference. Magnaflow has a good tech article that may help HERE that's one of the better reads I've seen.
As for injectors... Wow, what a stir that caused here and was it ever wrong! The stock tune will go pig rich into the 10's on a full power run, with the injector duty cycle hitting near 90. GM knew that, but knew that was no real problem either. Find a tuner who knows what they are doing. A good tune will put the AFR where it should be and the IDC will come down, even with a raised redline and mild mods. There is also a considerable delay before power enrichment (PE) hits. A good tune will make more of a difference than most single bolt on mods you hear about.
A sensible list of bolt on mods will add power, but don't really expect much N/A without going into things like cams, porting, larger valves with springs, etc. Then drivability and mileage suffer. Only boost will make any real gains and with that comes other problems with such things as reliability.
Take your time. Don't rush. And... HAVE FUN!! Sure you'll make some mistakes along the way (hell, I did!).

Get the GMPP cat back its perfect for our car. Also you can try a CAI if you want but I have, and like my GMPP intake. I'm also getting the CA header and keeping the stock down pipe for the emisions warrenty (for now
) the after market down pipes are too much for too little gain IMO.
the GMPP intake, cat back, CA header and 2.0 injector swap and tune (IF you can get it to work right!) should put you at a damn near flat 15 in the 1/4 mile. Theres more then one of us 2.4 guys running this setup and that what were all trapping so you should be there too.
Me? I'm waiting for the Hahn turbo kit to come out and then I'll be in the 13's.

well im running the ca header and its a beauty. very hard to get in though. be sure if your tuning midaswell buy an exhaust and dp. i bought the ca highflow cat dp 2.5 is plenty. the header has 10 nuts and you cant get a torque wrench on them. you have to use a 1/2 wrench open end and box end for some. it takes about 1hr30mins to take old off and put new on. and if you do by some CHANCE figure a way to torque them which you cant then the ft/lbs isnt read in ft/lbs on our aluminum blocks the head is torqued at INCH/LBS its like 250inch/lbs it converts to 7 inch/lbs for the header nuts. but i just felt the how tight the nuts were on the stock header and then tightened them to the same tightness on the new one then checked them a week later and then 2 weeks later you should be good to go. make sure you use all new gaskets. you have to take the dp off the exhaust to put the header on. you have to put the header on from the bottom and have a guy on the top trying to put the nuts on. the guy on the bottom has to TRY TRY I SAY to fit the header onto the block studs. its very hard to get it on the studs for some reason it doesnt fit right. anywhos yes its very good buy for 220$. the dp from them is amazing too so thats 290 for 2.5 highflow cat. anything else you have qs about exhaust work and parts i know see you later.
ryan.
i also like the injen intake better than my gmpp intake. it looks better but the injen doesnt have any brackets it just sits there. you can fasion up your own bracket for it though. but the injen is cheaper too.
ryan. ooh and it works the same. and i think its better.

Agree on the difficulty in torquing some of the header nuts, but 
with your torque numbers??
The spec is for 124 lb-in.
There are 12 inches in a foot.
124 lb-in = 10.3 lb-ft.
