congrats and welcome to the site
u should have fun with your tour...look around the site and u'll find lots of options on what u can do to it...for 500 u can do cold air and a chip or maybe u can get a decent exhaust system for that although the more popular kits (cat back systems)used by some on this site are more in the 600 range i believe
others can give u more insight...meanwhile just read around and someone will answer any questions that may come up for u
