This page has specs on the 2.2 automatic, but it is for the coupe and not the sedan.
7.87 seconds and 16.18 for the 1/4 mile.
The Car and Driver magazine says the sedan's 0-60 is 8.4 seconds.
They might have tested it at a higher elevation though, who knows.
With a half second slower 0-60, the 1/4 mile might be close to 17 seconds, anyone have the sedan's 1/4 mile time for stock?
With the exhaust and intake, you should have about 25 or so more horses.
I was told in a car that weighs 2800, it takes 30 or so horses to shave off 1 second on the 0-60 time. You weigh a little more than that and I don't think you have not gotten to 30 horses yet (could be wrong).
What does all that mean?
You probably with the bolt ons took your 0-60 from 8.4 and knocked 2/3s of a second off and should be around 7.74 seconds. Of which the 1/4 mile should be less than 16.18 and more like 16 seconds flat or so.
If the computer is not reset,or that K&N intake is causing problems for the intake sensor, or possibly even a sensor in the exhaust is giving a bad reading from either a sensor being mounted wrong, damage from install or even a loosened wire, this will make your car slower than stock.

Yes if you send the chips you want dyno tuned to nelson performance here in san antonio, their the only guys in the country that can tune 2.2s. They can change any and everything you need to be changed. Once you pay the onetime tuning fee, you get free retunes for the cars life.

i don't know which misinformed sites you visit but ricer math is saying "my intake claims to give me 15 hp and my magnaflow muffler claims it gives me 20 hp so that means i have 35 hp."

Everybody in here other than the moderator and a few other people don't know what they are talking about....The tq on a 2.2 is low....so low that with an automatic it barlye pulls out of the hole at all. Yes automatics are better to drag race but when you actually have tq....
You said you gutted the interior in here, does this just include the passenger seat and backseat? That is not gutted BTW and in no way equals 100 lbs maybe 30 but thats about it. As said my cavalier 2.2 ecotec with an automatic which the cavy's are ligther than cobalts ran a 17.1 at 81 mph before I got nitrous. Your cobalt is slow because it is a 2.2, sorry guys 2.2's arn't that great unless you go the FI route.
If your car was a 5spd it would be able to launch a whole lot better becuase your small tq convertor would not be hendering how much you could rev it up on launch. There is just not enough tq with a 2.2 ecotec to get a hard launch from an automatic. Plain and simple.
Also your intake and "fart can" is probably only giving you about 5 hp over stock....that won't even equal a .1 of a second....

17.1 in an automatic 2.2 is slow...cavaliers don't have the exact engine i'm guessing, i believe chevy changed things, said the cobalt engine was built much better, that, or they're heavier. Theres a guy at my local track running 16 flat with an automatic 2.2L cobalt with intake and full exhaust.....NO weight reduction......
look up the how to launch an automatic.

To the OP, get some more, real, power mods instead of just a muffler and learn how to launch your auto. I would look into getting the SAI removed, and getting a nice header, dp, and full exhaust. Hell, you can do it ala cheap, and get a used LSJ exhaust mani, dp, and exhaust. And one time slip doesnt make your car slow. You can go to the track one day and run x.xx and the next day you may be faster or slower.
