hey everyone, just got discharged from the military for lie'n about some medical history so i came back and needed a car. i bought an 09 cobalt ss/tc for 17,900 and it only had 6k miles its completely blacked out and sexy as f. anyways glad to be apart of the forum and honestly can say im very impressed with this little car. one question has anyone done the air box mod on the turbocharged ones? when i had a speed3 and sti i heard it was a good idea so anyone done it on these? (till i get an intake) im thinkin the order of mods should be intake, springs, downpipe, catback, tune? is that a good route or no? also is there an pnp tuning system out for this car?
