Are you talking about removing the section of pipe including the resonator? I just got the mufflex 18inch muffler kit and kept the resonator. Great sound when opening it up and not too loud when idle, but a nice mellow growl (and pretty minor drone, doesnt bug me at all).
In the winters when it hits down to -40 we usually have to warm up the vehicles for 20+ minutes so i didnt want something that would **** off the neighbors. The 18 is perfect for me, and not so loud that the lady hates it lol.
Im sure if you wanted more sound you could just remove that section, but that water boiler size of a muffler dodge put on there will likely keep it pretty tame regardless if its still on
