Driving over rocks no longer makes the 'ping' noises and the stereo sounds much better. I did this back in 2013 and have since added an exhaust. I think the deadener really helped cut unwanted vibrations in the hatch floorpan as well.

I used the same combo. I still need to do the doors, but doing the back half of the car made a big difference. It's the foam on top that does most of the work.
