Good sounding low growl to it and has a lot more throttle response to it as well

The super 44 series flowmaster worked perfectly for what it is. I have a 2014 6.2l fx4 f150. The sound you get is amazing... although it's hardly louder than the super 40 series. So if you're going for loud I would go ahead and get the 10. My gas milage jumped up 2 miles per gallon. Great easy add on for any truck.
