There's a lot of threads on here for various mods. It depends on how much you want to spend. Headlight upgrades start around $35 with ballasts. Air intake for a little more power and sound is a couple hundred. If you plan to do mods, you'll want to get it tuned after and the guys at Orange Virus have been the choice for many of us on here... their price now is 499. Also there's lowering springs & low profile wheels varying im prices. But that's just my input...
