Hoping for an up to date muffler option to replace stock

Start from the cat and attach a short piece of pipe ("nipple") then attach the longest "cherry bomb" type (aka "straight-thru") muffler you can fit under there and attach the stock tail pipe (or a generic tail pipe of the same size and shape that will allow you to fit to the muffler.
It will be louder, but shouldn't be too bad.
You could also just pull the mufflers and run straight pipe out to the tail pipes.
That will essentially do the same thing, but will be a little louder.....it will, however, be a little less expensive proposition.

I did notice the exhaust config is a little strange.
There are two pre cats on one bank and one pre cat on the other bank.
From there, they merge and hit a cat, the O2 sensor is after it.
Then, oddly, it hits another unit that looks just like the cat, right after the O2 sensor.
Then a foot or so back is the huge rear muffler.
Taking out the rear most muffler probably won't make it too much louder as you say, but there may be some lack of refinement to the sound.
Does anyone know for sure what each unit on the exhaust is?

They're all cats.
Pull the muffler, but remember to run the exhaust full length. If you just put a little turn down coming a few inches out of the rearmost cat, that's what makes it loud.
The longer length of the full length exhaust is what mellows the sound...that, and plumbing both banks of cylinders into one pipe.

Yes, it does.
VW did tests many years ago concerning this.
They found that the fewer cylinders that are plumbed into a pipe, the easier it is for the ear to pick up each individual "pop" of the exhaust.
The ease to distinguish each cylinder popping off is what gives the illusion of a "loud" exhaust, or at least one with a "sharp" report.
You hear, "pop, pop, pop...", instead of "poppoppoppoppoppoppop...".
It's the same trick of the brain that makes movie film look like actual movement, when projected on a screen.
Just like all those pictures on the film strip running by so fast that the brain can't process each one individually, the same goes for the report from each cylinder.
If you jam them all together in one pipe, the brain can't process each cylinder individually, so it hears it as one long drone.
...another thing you could do (not sure it will work with your truck, though) is to bend the end of the tailpipe down at 45 degrees so the report is directed at the ground.
Then what you hear is what is known as a reflected signal.
The reflected sound has less energy to it, so it seems quieter. Also, most of the squelch is removed from a signal when you bounce it off something first, so the sound is interpreted as more "pleasant" than hearing it straight from the source.
Anyway, I'm starting to ramble, so I'll stop for this post. Hope all that makes sense.
Feel free to ask anymore questions if you have any.

That's all good information, thanks for helping out and answering - i must say, it seems most of the ranger boards have almost died, shame as it looks like they were a hive of activity and information several years ago. Bad timing for me i guess.
Alright, so probably the cheapest plan to get more noise, or report from the stock system, is just to replace the muffler with a straight through pipe to the same length as the original.
