Hi,anyone out there swapped there exhaust system for the adamesh stage 2 middle section and the stage 1 rear back box removal,my 2007 xkr portfolio already has the middle section done and was thinking about removing the back as well and replacing it with the adamesh rear pipes but wondering if it might be too loud,anyone done this,adamesh say a few customers have done both but they don't recommend it because of the loudness,anyone out there done it?love to listen to a video of it if you have
