If you're bored, do the delete. If you want to make a noticeable improvement, get a cat-back exhaust. If you want more improvement and still likely e-test passable, get a high-flow catalytic to go with the cat-back exhaust.
Personally, I'd go with at least the cat-back. On the stock manifold and catalytic most systems don't make the car that much louder and you get a few WHP for your trouble to go with the much nicer sound.
