I had a 60 series on my 4.7 durango.
The 44 is the lower of the 2.

I didn't know that the 40 series was available in the f-body style stock configuration. On all other body styles though, the 40 series is definitely more aggressive. As a matter of fact, it's the loudest street legal muffler flowmaster makes. (street legal meaning chambered)
