Loud but good would be remove your resonator and replace your mufflers with summit race welded, dynomax ultra welded or magnaflows. If you ever plan on doing a DP, keep your resonator. Hear my sound clips here:

OK, it is not my thing, but it sounds like you are young and may enjoy the sound, so I have heard a lumina with the 3800 who had kept the resonator but went with small glasspacks (18") instead of mufflers with chrome tips. It was rather loud and abnoxious to me, but a lot of teens liked it.
