yes I know I have been slacking.
I used 7 sheets inside the trunk and 3 under. This does help quite a bit with the noise. For me it was a perfect solution because I wanted to keep my RPI exhaust. I want to be careful about recommending this for these reasons:
1. You are adding weight to the car.
2. It is a huge PIA to take the trunk area apart and very likely that you may break some of the interior plastic pieces while doing so. This will result in unexpected costs.
3. Once you install this stuff it is not coming out, so you are committed.
All that being said, it worked really well. It does not eliminate the drone and cabin noise; but rather, brings it down to an enjoyable level. In my case I have no problem taking the M apart. I actually kind of enjoy it. The RPI's are so much lighter than the stock mufflers that I did not mind adding the extra weight over the rear wheels either.
