Installed on my 2002 Ford Mustang and did notice a reduction in noise within the cabin. It takes patience to install, it’s not hard to do and sticks very well. Covered more than half the vehicle and still had sheets left over. You can feel the quality, it is pretty thick and feels heavy which is what you want. I think it’s worth the money.

As long as the surface is thoroughly cleaned, these mats will stick to just about anything. They provide my car with a tremendous amount of sound dampening and have made riding in the car 10 times more enjoyable. I drive a Toyota Yaris and although the engine is built like it's meant to last forever (imagine that), the rest of the car is not of high quality. Which means we used to get A LOT of noise coming from the road, other cars, etc. After I installed these mats which, by the way, I wasn't able to install on every surface I wanted to install them on (due to lack of tools to be able to disassemble certain parts of the interior), the noise coming from outside the car is nearly completely gone. I covered the underside of my hood, the entire interior part of the hatchback, most of the floor in the trunk / spare tire well, and the entire interior side of the doors. The parts I couldn't get to (or didn't want to) were: the ceiling, underneath the driver & passenger seats, behind the dash and the floor for the 2nd row seating. As you can see I left a lot of surfaces untreated with this product AND STILL it blocks most of the sound. To note: people recommended getting the roller tools to help install these mats. I got a few of them in different sizes and they worked O K. Not because of the quality of the tool but because some places you need to install these mats in don't have enough clearance to use the tool. That being said, for the larger surfaces, the roller tools help a lot. Also I found it very beneficial to use aluminum tape while installing these. The tape I used is specifically designed for materials that undergo high temperature changes (like your dryer vents, etc.). This wasn't because the mats were not sticky enough but because there were some places I installed the mats with small gaps between them. I'd also recommend getting some kind of fluffy insulation-type material for large spaces that need noise dampening. Rock wool, for example, worked great for me. As an example, the interior sides of the 2nd row seating walls had large spaces between the plastic interior cover and the metal part of the car wall. I'd install the mats on the metal but was left with 6" - 7" of space between it and the plastic cover. I chose to fill those spots (and spots like it) with insulation which provided EVEN MORE noise dampening.

I’ve used this product on several cars now and everytime I’m happy with the results. It’s durable, the adhesive is awesome even if there’s a little bit of dirt, holds up to temps and other factors very well. Installs very easy. I recommend getting the rolling tools for a good seal and getting seam tape as well. I usually use the aluminum hvac tape as it’s half the price and way more durable. This stuff is awesome and I will keep buying it for all my projects!

The Silass mat works awesome! I picked up 3 sets but doubled up on the floor so I’ll need another to finish the little bit left. It made my Jeep Cherokee XJ sound like a new car. It was noticeably better insulated and the sound is so much better. The noise is more dense sounding instead of rattly which I love. It sticks like crazy! And it was super easy to install and trim when needed. Wish I’d have put this in every Cherokee I’ve had.

Applied to the floor of an old Mustang, was concerned about not being original, but once I started using them I could see the value. One, the floor pan will never rust they went down like a solid membrane, easy to cut and apply. Car sounds more solid even closing the doors I could hear the difference. I will be using these as part of my inventory and problem solvers.

I’ve used dynamat in the past. I like this every bit as much as the dynamat. It’s not as soft or sticky, but I prefer that it’s a little more rigid and the thickness is great. Sealed up the doors and does a great job on the door panels. Sounds solid. Can’t wait for the summer to see how much it helps keep the heat out from from the doors. Great value for the money!

I like it, it worked great. It does not seem to have any bad smell, although it has a slight scent if you put your nose right up next to it (but all brands are like that). FYI if you don't already know, most of the noise comes from the wheel wells so DO THE WHEEL WELLS FIRST! And you probably don't need to do anything else besides that because 90+ % of all the noise comes from the wheel wells area (from road noise as the tires roll on the road and vibrate the air). Don't bother with the floor, the doors, the trunk, or the roof unless are looking for that last 10% of improvement because you are a car stereo enthusiast (or you like to waste money and do extra work LOL). I put multiple layers of butyl sound mats totalling about 1/4 inch on my four wheel wells (plus about 2 inches farther around the perimeter of the wheel wells), and just a little bit on the front floor (driver and front passenger floor) but I probably didn't even need the floor. The wheel wells made a HUGE difference. My car had NO sound insulation whatsoever and was horrible to drive on the highway, now it is PLEASANTLY QUIET and a joy to drive. I actually also put alot of sound mats on the middle and back floor, but it didn't make any difference so I removed it. So I recommend a minimum of two 80-mil layers on all four wheel wells, but preferably four layers to total about 1/4 inch. Or use three layers of the 120-mil mats. The more the better, but it seems to me that 1/4 inch is enough to bring the noise down to a luxury level.
