i drive like a asshole and i deliver pizza's at the moment and i get great gas mileage you just gotta know when you push the pedal to the floor and when not to lol
is a header or straight pipe better for performance wise or does it not make a difference. how much did u buy ur straight pipe for>?.......and for the dc sports turns out my brother doesnt need hi off his 2007 honda civis si and i might be able to make that one fit on mine.
no i did do research but i wanted a answer from people that own cobalts as well so before u start being assholes findout why im asking it...because many different websites told me 5x100 or 5x110 so... so much for research right i dont wanna buy the wrong part.
