Looking to do this for my truck but I will cut the 3M. What are the quantities that you used? Also what about taking the truck apart? Any good guides or anything like that?
Want to cut the noise as it is annoying me for some reason.

4) Using an old FLIR/Extech 40K series SPL meter, the interior SPL is now measured at 64 db driving on IH 20 at 75 MPH using OE Bridgestone Dueler Aleza P275/55r20 from the center console position. The SPL measurements had a variation of +/- 1 dB as measured from the front passenger position and the rear driver and rear passenger side position.
I conducted the same measurements on a recent trip. Ambient temperature was 44 degrees F which as we all know, the cooler the air the denser it is which means sound travels farther.
Driving 77 mph in rough pavement my SPL meter never climbed past 58 db. The only difference was that I added thinsulate to the A pillars and the door mirror covers.

Just got done putting down some Noicio sound deading myself. Even wrapped the OEM Sony sub box but forgot to take a picture of that. I will eventually seal up the opening in the doors with acrylic . Made templates of the water proof plastic to accomplish this.

OK so I said a while back that I would measure in cold weather. I measured in hot weather and the performance was good.
Cold weather was just as good. We hit a max of 28 degrees ambient temp today. The garage was holding steady at 35 degrees and the truck as a (comparatively) warm 50 degrees. Once the heater got working and the interior temperature was a toasty 80 degrees, I turned it off. After my 30 min commute, the temperature had dropped to 75 degrees.
I am super happy and glad I went through the work. If others follow the examples, you can expect similar results. Just take your time and do good work, dont cut corners.
Its worth it.

Apparently everyone knows this but me, but what do you mean by disconnected the fake engine noise?

I just went through this, I did the entire cabin, from firewall to rear wall, doors, roof and floor.
Dynamat et al are CLD, constant layer dampening, and they resolve the noises caused by rattling/vibrations/etc. The third layer addresses airborn noises, such as air leaks, road noise, etc. Those are addressed by dense absorbing materials.
In between, you have layer 2, which is a decoupler. This helps physically separate the CLD from the sound absorption and eliminates the transference of resonant frequencies which enhance the noise.
Layer 2 is a CCF (closed cell foam) that physically separates the leftover vibrating panels (dampened by your CLD) from your sound absorption material.
For CLD, I used noico 50 mil from amazon. It is OUTSTANDING material, very easy to work with, and the butyl is miles ahead in quality than dynamat is. I also used fatman in strategic places, and its almost as easy to use as Noico. Noico is extremely economical and your TCO is hundreds of dollars less than any other material (dynamat, fatmat, roadkill, etc)
I covered the entire floor, the roof, the rear panel, as much of the firewall I could without yanking the dash out, and the interior AND exterior panels of all four doors with Noico 50 Mil.
For the floor, I used CLD, followed by the same CCF, and then used 1lb/ft^2 mass loaded vinyl. Its the same material used in professional recording studios and as such, it is extremely heavy and absorbs (again using ASTM E1050) all frequencies from 55 Hz up to 5.5K Hz with an efficiency coefficient of 92%.

I would recommend their luxury liner pro if going to lay down some mlv as it already has CCF decoupler bonded to it.
