Who has one of these mufflers? I ordered one a month ago and it's on back order.

I was curious what you guys think of them. Do they have any drone? I tow some heavy loads (15k+) and I don't want drone. Where did you install it? I was thinking of putting it where the stock muffler is. On a scale of 1-10 (1 being stock and 10 being straight pipe), how loud are they outside and inside the cab? Thanks in advance.
