Best bang for the buck?

I have about 100-150 bucks and my car is brand new. I have a 02 civic ex 2 door it's a 5 speed and blah blah blah. Everything is stock absolutely no mods. It needs tint like no tomorrow so I'm going to get that done first DEFINITELY. Anyway, what are some recommendations for a very good mod at my price range (100 dollar range). I've looked at intake and stuff but I know alot of people have done that and they said its more of a cool noise thing. I might end up just spending all that money in appearance but I wouldn't mind getting my car a little bit faster. The engine hasn't quite set in so I haven't really seen what it can do yet. All I know is it is bitchin fast on the freeway! Well, thanks for the suggestions.
