My name is Justin and i own a 08' Cobalt LT STOCK. Im looking to mod it up a little, and trying to keep it carb certified as much as i can. I have little hands-on experience on how to do it myself so someone else will be doing it for me, but I do understand car talk for the most part. If anyone has time and can help me out on where to start i'd appreciate it. I've been looking around for a nice intake and exhaust that give good gains without killing my milage. So if anyone has time id appreciate some help. THANKS!
