Here's a somewhat technical definition that I found online and feel is accurate.
"Exhaust drone is that which is caused by harmonics- a soundwave generated which in essence takes the exhaust sound and sends it back up the exhaust system (towards the engine) and is released or transferred into the passenger compartment."
Drone usually occurs at a very specific and narrow window of RPM and throttle position...typically while cruising on the freeway. It is generally an intrusive tone and due to it's continuous nature at a given point can become quite annoying. Some people are more sensitive to it than others.

I don't know how the MF compares to the FM but I can compare the MF 14 to the MF 22 as I have ran both. The difference in overall volume between these two mufflers is noticeable but not as significant as I would have expected. The difference in drone at freeway speeds however is an entirely different matter. I replaced the MF 14 with the MF 22 for this very reason. Even though they never complained, I felt sorry for my kids having to hear that mess in the back seat. I personally detect zero drone with the MF 22. The vast majority of MF 22 owners seem to agree although I have seen a few that said they had slight drone even with the MF 22. Once again, personal perception is at least a small factor.
I do know that whenever the day comes for ol' silver to be traded in on a new Ram, a MF 22 will be the first mod.
