Suggestion: Think about going to a few NASA high performance driving schools to hone your driving skills and open up a whole new world of fun for yourself.

After doing that for a while, you'll have a greater appreciation of what the car's capable and what there is about the car you might want to change.

If, however, you really must spend $2000 on car parts, my suggestion is to get a high quality header and 2.5" cat-back system.
