Air box and filter is still OEM from RAM. Have a K&N sitting in the foyer but somewhat afraid to install it. I know, I know, all will be fine....
I'll add some miles and offer my opinion soon. Pics coming too if you all think it would add value.
Your K&N will have more volume that your muffler
I had both paired previously as well.
Still have my 22" though.
Nothing unbearable....just under WOT, you really hear that K&N
