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.

Arent they called Boorlo's ?? Like a trumpeting effect...

PA only hooks your car up to a computer and makes sure there are no CEL faults and that all of the emission related sensors are in the "READY" state (meaning you didn't JUST clear a CEL before coming in)
They also do a visual test for a cat, but that is it.
You can get noise complaints for no mufflers, etc, but not during inspection.
I would say get a cutout installed if you want loud at times.

Ahhh...you mean one of those little imports that you can hear coming from 3 blocks away? The ones that are revvin' 7 or 8 grand and traveling at a blistering 32mph? Yep, those big, loud pipes did wonders for their performance...

Too bad a lot of those fart pipe wielding imports are faster than an N/A 3800...
