I have true duals. Mandrel 2 1/2 and balance pipe with Super 44 Flowmasters, pipes dump over the axle by the spare tire. It is louder than I expected but not a bad sound. Really sounds good when you put your foot in it. I don't know how to answer about drone I would say no but to some people it might be a little much. I have other vehicles that are much louder but they are not daily drivers. I don't have a good way to get a sound clip or I would share. I'll see what I can do.
The simplest way to get what your wanting is to run dual in dual out 22inch magnaflow, the xpipe is in the muffler. I dont own this setup, but prob will be my next. Quiet cruising, rumble when u step on it
