Heres just a few suggestions...
More sound? install a cutout, or remove the mufflers. Don't think you need mufflers to pass emisions, but i'm not familiar with PA laws.

I can't believe you actually want more sound. In my experience, Magnaflow glasspacks do nothing to mute exhaust noise - they're as good as straight piping. People use them to have muffler on a technicality. I suppose it sounds better on a V8, but with DOD it could sound bad?
I think the cut-out was a good idea if you want loud, but the 3" exhaust was a better idea because it will just lower the exhaust noise pitch...

If you want loud get rid of the Magnaflow mufflers and install some Porter instead:
Porter Mufflers
I completely understand people going with a 3" downpipe on SC and V8 applications in a W body, but why in the world do you guys keep suggesting that people put 3" exhaust pipe on their cars?
3" piping is way too big for a 3.8 and even a 5.3 unless its had some modifications done to it. Sure, you may get a slightly lower exhaust note, but the larger pipe hurts performance. It decreases the velocity of the exhaust flow which in turn reduces the scavenging effect of the cylinders. The result is greater dilution of the incoming charge which means less power is being produced. If you're building an all out track only car then go for large diameter non-restrictive exhaust, but it really doesn't make much sense to install large pipes on a street driven vehicle that needs to be able to perform in a variety of rpm ranges. If you were churning out 400+ hp larger exhaust would make sense (to compliment/enhance internal engine mods), but for a daily driver that is basically stock you're just going to hurt performance,,,but it will have a deeper tone at idle.
