My 21 gen 3 is pretty quiet to me... I'm coming from a 19MY ram with KO2, and also a 20MY ram stock big horn trim.
19MY ram with KO2 was very loud. No doubt. 20MY ram was quiet, because it was stock.
This raptor is quieter than both, and it has 35" KO2.
The only time you can hear them, and actually make it loud is when you put it on the "slippery" drive mode. Slippery drive mode turns off ALL types of noise processing, I think. So it turns off the annoying kind (fake engine), and also the good kind (hides the wind noise and road noise).
So drive it in slippery mode, put exhaust tone to quiet, and you will hear the real noise. The other drive modes should be quiet... at least it is for me.
Or, dont drive in the left lane all the time, where the middle boundary acts as a mirror and reflects all noise back to you.
