Dynapad

I just fully restored the interior of my foxbody Mustang. Between the supercharged motor, full exhaust, and very firm racing suspension, the car is LOUD inside and out. After stripping out the entire interior and trunk down to bare metal, I first applied a Foxbody coupe specific matched Dynamat kit from Late Model Restoration. But there were a lot of flat metal panels left untreated, and flat panels are what tend to vibrate the most. So I got a couple of generic Dynamat kits to cover more area. And then I put this Dynapad over the Dynamat on the floor pans and able hump area. Overkill? Maybe. But considering how loud the car is to begin with, I figured it couldn’t hurt anything but my wallet (this stuff isn’t cheap, haha) and maybe the penalty of added weight (so what, it’s a light car with over 670 HP and nearly the same in torque, so what’s an extra 90 or so lbs of sound dampening?). I can say that even with half the interior still out of the car, the reduction in Noise and vibration is noticeable. The car is still loud as hell, but to a lesser degree and the exhaust drone isn’t as palpable. So while not cheap, this stuff works, and is very easy to cut and install.

I was looking for a way to cut down on the road noise in my C6 convertible. I bought this mat cut it to fit and placed in the trunk, cut the noise tremendously. I'm a second one to put behind the seats to cut more of the noise.

Why did you pick this product vs others?: Has always been the my product of choice. Others have imitated and often sell for a good bit less. When compared side by side Dynamat is the clear winner..

Unlike the Dynamat series which is really just for high pitched vibrations like clinking or metal tapping. This Dynapad stuff is incredible for not just vibrations, but blocking sound almost entirely. Definitely head their warning of the weight, it's very dense and very heavy which is great and is what makes the sound blocking possible, but if you're installing the pad on anything other than the floor itself. heavy duty adhesive won't be enough to hold in in place. I bought it for the backwall of my truck, and luckily I had already planned on using the bolts that were there for support. This pad works so well for blocking sound that it's quieter now than it was with both the stock sound deadener and back seats and I haven't even put the back seats in. This pad is strictly for vehicles that are just loud in general, I highly doubt typical vehicles will notice any real difference unless they stripped it down to metal. My truck is lowered with headers exhaust dumped right after the cab, a lot of sound bouncing around in the cab. It was a dramatic difference. I also put a full coverage layer of dynamat below the pad and drove it around before putting the pad in and quite honestly the dynmat did next to nothing for the sound, just little tinks here and there.

What I like: I only had the Dynapad installed on the engine tunnel area and it has already made a HUGE difference to the annoying sound level. I wasn't able to listen or speak on my speaker phone before. I only had the dynapad installed on the tunnel area where most of the noise and heat comes from. It has made a big difference. I cut and installed it myself. The carpet is heavy and sit well on the engine tunnel. I do not want to use glue on the carpet as my restored BJ40 is known and very prone to rust. I am afterall living in a humid climate. This is NOT a closed cell foam. It's very porous, so I would use this on area where water will not sit or stay stagnant in case water seep unknowingly in from some where. The lighter side foam absorbs water. The darker side is more resistance to water. I will be using Dynadeck for the rest of the car. What I dislike: Its bloody expensive for a small carpet for a 32 x 54 in.

I am writing this review for all the people who are on the fence about getting dynamat and dynapad for their car. I have both us these products in two different cars. It has made a very big difference in both of them. Car number 1 is a Nissan 240sx fastback with a sr20det turbo engine and a full 3 inch exhaust. Car number 2 is a 2016 Toyota Yaris 2 door hatchback. You will need to get at least 1 mega pack of dynamat extreme to do most of the car. 1 mega pack did the entire floor, roof, trunk area and rear quarter panels of my Toyota Yaris. I will need to get some more to do the two doors. I used 2 rolls of dyna pad in this car. I used 4 rolls of dyna pad in my Nissan. 1 roll just for the fastback area. If you only use dyna mat its good to about 30mph. At highway speeds you won't really hear a big difference. That is where the dynapad really helps. The faster you drive the more road noise enters your vehicle. If you are sitting in either car and they are not running they are extremely quiet.

This mat is very dense, very heavy and easy to work with. However the price is high and for it to be effective I think you'll need to cover your entire floorboard with this stuff. I used it and the Dynamat Xtreme to covert the front driver and passenger foot wells and didn't notice a tremendous difference. But then again I have a late model car, if you're trying to quiet an older car then you might get a better ROI. I do know that the Dynamat Xtreme does in fact deaden resonance in the doors but since the floor is already stiffer and has features (meaning it's not a flat piece of metal) I'm not sure if it's as effective on the floor as the doors.

Used this to replace some removed sound deadening in the compartment behind the seats in my 350z. The material is super dense and heavier than you would expect. Worked very well. I can see it would be really great under you carpets as well. Worked great and got rid of that drum echo happening behind my seats.

Works great. Heavy.

Just bought a condo and the fridge was making a loud vibrating noise from the bare floor. Placed this order underneath to help. Very happy with the results.

Dynapad is the greatest material to use for any requirement to lessen noise and heat in any car. I used it on the floor boards front to back on top of Dynamat extreme. What a difference it made on the inside quietness of the vehicle. I would recommend this to everyone as a great underlay for carpet in any car. I did find that fitting it on contours can be a little challenging, although with some planning and trial fitment before cutting helps.

While expensive for the area covered, the Dynapad is definitely a strong noise absorbing mat. Too bad it is so expensive. Too bad also that "Loaded Mass Vinyl" is both expensive and really hard to get in Canada."Loaded Mass Vinyl" would have been my material of choice but ordering and getting from the U.S. with customs and extreme shipping fees (heavy material) make no sense. Nonetheless the Dynapad does a good job.

Great Product!
