Not related to the third row delete, but related to sound dampening, don't remove any of the plastic under the hood, wheel wells, etc.
No one piece of all that plastic matters, but as a whole, it works to help keep outside noise down. If one were to remove all that plastic, there would be a noticeable increase in cabin sound.

i used 80mil(2mm) sound deadening from amazon. i honestly don’t know if it helped. i would go thicker if i had to do it again. i did the entire metal area after the 3rd row is removed.
I got this. https://www.amazon.com/gp/aw/d/B07XJ5MVQ8?psc=1&ref=ppx_pop_mob_b_asin_title
Will be tackling this project after the holidays.

oh yeah, i did the trunk door too. i had to remove all the panels when i installed by fold down table so might as well do the sound deadening too. i used Siless brand butyl.

On the 460, can you open up the flasher module and grind down the resistor wire/hoop with a dremel like on a 470? That's what I did and it worked perfectly to get rid of the hyperflash issue. Not sure how much that system changed for the 460.

I learned more about sound proofing than I ever wanted to know with my Polaris Northstar Rangers. From the factory you have to yell just to be heard to the passenger next to you in the cab. By the time I got done you could whisper and be heard, even going 60mph down the road with UTV off road tires.
@RJinVA is correct, Butyl is just for helping prevent vibrations transmit through the floor. You only need 25% coverage to be effective and 60% coverage gives 95% efficiency in preventing sound, which is vibrating waves, from coming through. Luxury cars have been using it for years, look at the 3rd row floor with a base model.
Compared to the Luxury and higher end trims in the GX
You don't need much of it for it to work.
But you need mass to actually block sound and that is what the seats do. The brackets help with structural integrity and prevent vibrations as well. Luxury vehicles also have perforated seat coverings to allow the sound waves to enter the mass and absorb sound.
Heavy equipment operators including farmers driving tractors don't want to listen sound all day and Tractor Interior Upholstery in Iowa sells bulk materials a lot cheaper than car audio enthustics and where I got my materials from. Butyl as a base for vibrations, I used Second Skin damplifier pro. Mass Loaded Vinyl next to absorb sound, there is that mass thing again. Then closed cell phone. I used MLV with closed cell foam laminate from Tractor Interior over the second skin Butyl.
I have a lot left over from the Ranger projects enough to do the GX 3rd row. But in the end decided not to rip out the seats in the GX even though I have all the materials including L tracks, etc. Once the Butyl is down getting the seats back in if you wanted to go back to OEM would be next to impossible unless you made allowances for it during installation. Then there is the MLV and foam layer. I found with my Taco that I ripped out the jump seats and sold 11 years later that the next owner may want the seats. For 3.5" additional height it wasn't worth it to me and I'm not a fan of drawer systems, they take up space on their own and you are restricted carrying what fits in them. Folding camp chairs, shotguns, etc. not so much.

That thick stuff looks to be able to really deaden sound.

There's decibel meter apps that you can download on your phone and then have hard numbers to look at.
Make a graph, plot all the points, turn it into a pie chart, then get the mean, mode, and median of the data collected, its standard deviation and your good to go!
Write a comprehensive test report and then share it with the group!

I used about 12 sheets. I pulled all the plastics to remove everything and stuck it everywhere I could. Made a big difference. Highly recommend.
Just used the generic Siless from.Amazon as others mentioned. It smelled very chemically for a few weeks.

So far everything has worked great. I slid my cubby back 4 inches so the middle row can slide all the way back and it leaves room for a gallone of washer fluid and my steel toes for work. The cubby then also touches the back of the seats adding another support member.
I am considering passing on a rear swing out and keeping the cubby permanently, as I can remove in 5 minutes if needed. Just takes 4 rated bolts to be removed.

You may consider adding a length of rubber tubing/foam tubing/carpet trim or something along the length of the box that rubs against the middle seat back so you don't get a wear line from rubbing on the seat back carpet.
