----For my Friend---- He has a cobalt ss 2007 (I think it's 205hp) and want to know if it's possible to chip it to have 260 hp like a 2008 and how much it cost. Does it damage the engine or transmission, etc..

does anyone know which exhaust systems give you what horsepower? eg. headers: pacesetter, DC, Vibrant CatBack: Megan, Borla, DC, Magnaflow, GMPP

I have an 08 Cobalt with an auto tranny and i was wondering how much hp i can run before i need a new trans thanks

Ok I was lookin at the ebay parts site in the sticky thread in owners lounge about links and they have like $30 chips that they claim add horsepower and mpg. Is this legit? Is it hard to install? Any answers would be great. Thanks guys (and assorted girls).
