You don't list very many mods, and I think that while the sound you end up with might please your ears, the resulting loss of low-end torque and throttle response will not please your seat-of-the-pants feel. Longtubes on a basically stock motored car won't help make power and make actually hurt you.
As for sound, I used to run Dynomax Super-Turbos, they were too quiet for my liking. I switched to a Flowmaster American Thunder cat-back and the sound changed dramatically...
