Set gear selector to manual 8, Carven 5" tips, Boral Pro XS 19" dual 2.25" out muffler and a ZZP ultra quiet resonator in place of the stock muffler is pretty good. I'm sensitive to drone but I like the way this sounds, deep tone. If I decide to finance the truck at the end of my lease I will prob do some sound deadening in the cab floor and back wall. Dynomax ultra flow catback was a great catback but it had a 23" muffler and 2.5" tail pipes with no resonators. I had to add the ZZP ultra flow resonator to my bola muffler as cold starts and at light load in some gears I got resonance which bugged me, I can't believe how much the small resonator helped and reduced the overall tone!
EDIT: I had a 18" maggy clone and it droned so bad on my 14 that I removed it within a month or two.
