I think we all agree the stock RAM exhaust is too quiet.
The real issue is where you live and what your tolerance is for noise in the truck and what your neighbor's and the Po-po's tolerance is for noise from your truck.
I am of the opinion that with the OEM 3" single in dual 2.5" out exhaust, only the muffler needs fix'n and even then, only by going to a straight flow muffler.
Here's where I expect to receive hate mail: you only need to drop down to a 24" or at most an 18" performance muffler to wake up your RAM and tell the world you got some Hoss's under the hood. Anything shorter has drawbacks around the neighbors and Po-po. I know some of the country folk can get by with the muffler delete or like a bypass, but once you get into population, its kind of a liability.
Sure you can spend big bank on long tube headers, and I'm not adverse to that route for performance.
But I think there are better places to spend that coin than a new cat-back exhaust--after all is mostly a bunch of new pipe with a better muffler that you could have installed into the high quality factory original piping.
Since most of us aren't building a 1/4 miler, straight pipes, or a bypass is (IMHO) over the top on a daily driver.
Of course, your live-in accountant/wife will probably have the most to say on how stupid-loud your truck can be and still work as a daily driver.
The guys over on the CRAM-ARROW forum point out they have similar drone issues to what we get on the RAM from the Hemi, and that their dual mode actuates
after the drone frequency is exceeded. So delete pipes don't solve that and a manual cutout might, but its just one more thing to fail over time and cost you money.
