Oh man, I was just about to post in the MBRP thread with a tip, specifically for you. I went on a road trip this weekend and when I was packing I threw a big thick blanket and a pillow under the time floor board, like on top of the spare wheel. That cut out a lot of the drone, sound deadening the trunk definitely helped with the booming that echoes above the spare tire. Right now I've got an old comforter under there acting as a sort of poor man's sound deadening. I wish I got this to you sooner, haha oh well I guess. Either way GLWS. and for everyone else, I absolutely love this exhaust.
