They all are a bit louder than stock and make more power, but the main thing is to get the complete cat-back setup. The stock intermediate pipe is 2-3/4" id and the aftermarket ones are 3" id so they flow better. I'm not sure which brands are still available, but the SLP Loudmouth is probably too loud for what you want. I had the ATR on my old 2000 SS and it sounded pretty mellow but was a straight through when you hit wot so it got loud during aggressive driving. Borla had adjustable plates so you could tune the sound to your liking. GMMG chambered had too much of a drone for me, I had it on my 93 Pace Car or 96 SS, I can't remember which one. Dynomax has a couple of options but the alumized ones will start to rust over time, that is what I have on my Silverado. Magnaflow is stainless so it should last and they sound pretty good.
