According to this comparison
https://ls1tech.com/forums/generation-iii-external-engine/119518-muffler-flow-db-comparison-hooker-maxflow-bassani-real-street.html
the Borla Pro XS mufflers would be the most quiet/sleeper. Next would be the Hooker Max Flows and Magnaflows. I found the Pro XS's for $85 each, but you'd have to PM me for the link since it's a non-sponsor site and I can't post it.

I have an incredibely quiet system, even with my cam. Here it is:
all mandrel bent 3"
Hooker longtubes, no cats
12" Dynomax bullets before the X-pipe (no restriction with these mufflers)
16" Moroso Spiral-Flows after the X-pipe
pipes under the axle and tips out the back
The main thing, IMO, is getting the pipes out of the back. I would say this setup was about as quiet as my offroad Mufflex y-pipe and Hooker catback. The duals just sound much nicer and meaner at WOT.

Eldebrock RPM muflers. They are around 3.6" thick, & quiet, until you get on it. This is what I run on the car for the street, then switch to a bullet for the track. Check out some pics in the sig. I think I have one showing the ground clearance.

Turbo mufflers suck. They arent quiet at all and are restrictive. According to the dynomax website the true 3" muffler is 5 1/2 inches tall and only flows 550cfm. THe 2 1/2" muffler is 4 1/2" tall and flows 450cfm.
The straight through mufflers flow much better. The 2 1/4" mufflers out flow the turbos with 700 cfm. For comparison a good 3" catback flows 2000cfm. If youre gonna go through the trouble of getting duals you dont want to bottleneck the power with crappy mufflers.

the quietest setup in my opinion without sacrificing flow is to use the 18" bullets. That's what I have going all the way to the back under axle. And car sounds very quiet at idle but roars under WOT. My main concern was annoying sound and vibration and this is the solution without affecting flow.
The 18" bullets are newones from dynomax and are 2.5" diameter.
