the difference is not "huge". I've only completed my rear hatch. I haven't finished behind the seats and on the floor, but you might get a few dB reduction. It is hard to say at what frequency, etc. The low rumbles from an aftermarket exhaust at the low-end of a gear is going to be loud no matter what.
