As people have already stated headers really arent worth the time, money and effort. I would save a little more and get the CBE of your choice and some test pipes or HFC's. Then save a little more and get it UpRev tuned. If you want to upgrade your suspension in a BIG way for a resonable amount of money you could spend $300 and buy some Swift springs. They are one of the cheapest/best mods you can do to this car. Good luck and let us know what you end up doing
