I have the same setup (single muffler, catless midpies, catless downpipes) but with an AT. It definitely drones below 2,500 rpm under load.

Getting a Magnaflow 11379 installed in the midpipes tomorrow, hopefully that will get rid of the drone. Thought about going the Vibrant route, but wanted something with more sound absorbing material as the exhaust can't be too quiet IMO.
