A. It has a cat
B. There’s snow
C. Most of the time the noise was pointed the opposite direction.
D. I didn’t hear or see anything over 2k rpms, tops, come out of the pipe.

But good sample of a single exhaust with a loud turbo muffler.
I can tell you dual 3” 40s even with full length exhaust behind a mild big block is a fair bit louder. And from your description, you don’t want a 40.
Slap a Flowmaster 60 or equivalent turbo type chambered muffler on it and enjoy some noise when you cob on it and mellow when your right foot isn’t as happy.
Technically, I had a very empty cat in that video.
This is the stock Y-pipe part with cat removed.

Looking in the pipe to the cat.
No catalyst inside the chamber...

To the OP, do what you want and report back on how you like it.
I bought the boy a welder and we have installed several mufflers on all kinds of stuff.
Some of it we like, some we didn't.
I had a single chamber Jones FlowPack on the above Suburban and it just didn't sound right.
It sounded fine, but after driving it for 100k with the Flowmaster on there it just didn't sound like my truck.
So we put a 40 series back under it for a while.
Then we found a single in and dual out Flowmaster in the junkyard with the tailpipes.
That went in and has been under there for a couple years now.

But soon, we will be changing it back to the single outlet muffler and exhaust pipe.
Just because we can.

You should do the same and try different things out to see for yourself.

I prefer 30 inch long glasspack with a short one upstream.

How would you describe the sound? And has it been like that long enough to "burn in" the glasspacks? I've wondered about doing something just like this for my Suburban...

It sounds great! With the vortec heads it has a nice growl to it. Nice classic tone. If end up redoing it, I will go with two long glasspacks, though.

An update for who ever wants to read it

I sticked to the Initial idea. I actually had a dynomax installed already. But a very dampening one.
Now have the trush turbo installed instead and that sound is great. A hint of that flowmaster tone, w/o all the drone and very acceptable at commuting speeds. Nice deep basetone and that bit of muscle notation to it. I love it
