I have a 2008 2.2 Cobalt Special Edition. Had it for about 3 months now and I've been saving to do some mods so I finally have a decent amount of money put together. I just bought a Pacesetter Header, an N1 Cat-back and a K&N Air intake. Im getting everything installed in about 3 weeks along with a 500 dollar dyno tune after everything's installed so I hope to adding a decent amount of horsepower. Ill post my progress and Ill post the dyno readout on the horsepower when everything's done.
