this might sound a little ricy, but a intake makes a pretty good diference,plus it takes about 20 minutes to put on, well five actually. you will be suprised. Get some nice lowering springs such as tein, skunk2,eibach ect. Stay away from the cheap ones. If you get a exhaust, try to get a greddy, thats about it, other exhaust are quiet, but if you have a vette, you probably hate that weed wacker sound, and greddy is very quiet. So are dc sports, and thermal. But get a greddy. Oh yeah get a strut bar, cause it makes the car alot more stable at 80mph on the highway when you go over bumps. They are pretty cheap, starting at 30 bucks, but a tune up is first, and watch the miles, cause a broken timimg belt, could mean your engine
