Exhaust sounds?

For starters, we all know the distinctive slant 6 sound.there is no mistaking it.
That having been said, among other things I need to redo the exhaust on my truck, as it is currently a home cobble job welded together from scrap elbows that came from the scrap dumpster at a local exhaust shop from the manifold flange to just behind where the rear cat converter was originally.(the truck used to have a pair of them, one a few inches from the manifold flange and the other in front of the muffler. The front cat had disintegrated, and it's guts plugged the rear one to a point of I couldn't get the engine to start/run with them in place. Then it had a stock type ~6 or 7" round and 20-some" long, typical "truck/rv muffler" behind the 2nd cat, and no tail pipe. Walker? Maremont? Who knows what the existing muffler might be? (Who cares it's going away)
This muffler is what came with the truck when I got it, and the truck also came to me with the tail pipe missing. Now mind you some of the scrap pipe I acquired is oem pipe from newer vehicles unknown, but most of it is the grade of stainless that more modern oem exhaust is made of, and in pretty good shape. . Despite that it welded nice with my MIG..
It is 2-1/4 from the manifold flange to the front of the existing muffler. What is there will probably last a while, but I know it is cobbled, I did the cobbling. (It helps tremendously having a 2 post lift of my own, I remember stringing exhaust on a floor jack and stands in past years)
I have a fresh engine going together for the truck, and eventually I will have to do something different with the exhaust, from at least ~a foot ahead of the muffler the rest of the way back. I'd like to do it all new from the flange to the bumper in 2-1/4, especially being as how I hogged out the manifold that is part of the super 6 stack that is going onto the new engine to that size. (I gasket matches it to a new, stock slant 6 flange gasket) I may have the tail behind the muffler go to 2". Will not have a cat converter in the system. Out in front of the back tire, or out to the bumper I am still up in the air about how I'm gonna want it to end.
Anyway, here comes the issue. Picking a muffler.
I know that I despise the flowmaster 40 series.sound. these were made for fox mustangs but sound like azz on anything else.
I want to "hear it" but I don't want it overpowering, and I definitely do not want drone.
How are flowmaster 50 or. (I think) 70 on something like this?
I have tended towards magnaflow on my v8 Dakotas, , but in looking around I see tons of magnaflow versions with the required 2-1/4 ins and outs. Oval, round, fat, skinny, long, short.
I don't want whisper quiet but I want to be able to hear the radio without putting an amp in the system. Ive had "muffler shop grade" turbos with true duals on my V8 D150s as well as (longer version) glass packs on others. When new, and not had a chance to "blow out" I love the sound of either of those options on a small block V8.
But I only want to buy 1 muffler, don't wanna have to swap it out in a week because I don't like it.
I am thinking I want to stay with something like a magnaflow but which one? Suggestions? Other brands comments also welcome.
