I have a 00 Ex and the first thing i tossed on was a short ram intake, its cheap and adds a little boost. From that went to an exhaust, once again, cheap, depending on where you get it done and what kind you get. The next thing I got in line are a set of Camshafts, you can probably get the parts and labor for over $300. As far as exterior, headlights, taillights, spoiler, tinting. All run for less than $200, so its pretty good.
