500 to spend, what to get?

AK370Z

What are you looking for? HFCs usually offers "best bang for your buck" but by installing them you get into the whole emission thing with the states (at least my state) and if you do not have to right tool, you can't install it yourself (not to mention the demon bolt ). Intake on the other hand will give your car nice growl on acceleration and are much easier to install. Intakes like STILLEN G3 give you about 12-17 HP. Since you've already done exhaust, your gains are NOT going to too much. So, it's up to you to decide what you want to install. My vote is for nice intake system. BTW, there are HFCs that are about $300. So, wait a few weeks, save up a little more and you can have BOTH!
