For the front bumper, you could switch to the 99-00 SiR front bumper with foglights, and maybe get a black mesh grille (lots of those available).

And if the look is all you want, spending the extra money for a good muffler will save you a lot of headaches (from the droning sound of poor mufflers) in the long run.
