Amazing difference after insulting a cargo van bulkhead divider

The sound difference is actually remarkable

I did not do the headliner but did notice a BIG difference in sound or lack of, driving on the road, and would recommend this product to everyone.

and once I did one door the difference was astounding

FanI actually did surround one of those mufflers with this sound deadening mat, just to see if it would make a meaningful difference, but it didn't

made an amazing difference in my 2013 GMC Sierra, i lined both front doors and i can't believe how much better my speakers sound

Made a significant difference in the sound quality of my music along with making my truck overall quieter.

Noticeable difference in dampened audio from my trunk, easy to work with and has good adhesive

So far I can hear a difference when driving down the road..less rattling, more of a quiet ride inside.

In my van, just after three sheets worth of applied product, we noticed a positive difference

The only reason I gave it 4 stars out of 5 is that although good - I wouldn't want to set expectations to high.

Surprised with the quality and how pliable these are even in cooler (50*F) conditions it still went on great

b/c the residue is very sticky.
