Celsus 10455 Dynamat Xtreme, Black,18" x 32"

I had never heard about this stuff: I have insulated doors & the boot floor of a Peugeot 107 & it makes a huge difference: It simply insulates your car, cutting out external sound that ruins your stereo listening & making all those rattly thin metal surfaces stop vibrating. It improves motorway driving by making the car quiet and far more relaxing to drive. It takes time to fit, is not cheap and does add weight to the car, but it really is worth it. Why pay for a louder stereo when this makes far more difference.

Product as described, very robust, easy to work with in flat spaces, would order again

I drive an 80's Toyota with a rather loud exhaust. I had seen Dynamat on Overhaulin with Chip Foose and decided to give it a go and I am very impressed by the quality, ease of fitting (except removing the seats etc from the car) and the difference it has made when driving, road and exhaust noise has reduced dramatically. It may be expensive, but in my opinion it is worth it.

Speed of delivery, Very easy to use.A penknife, craft knife or scissors. The product is easy to apply and certainly cuts down on drumming. Expensive but probably the best. Well worth it.

Sadly there are no detailed application instructions included in the box for some reason.It will definitely improve the acoustic quality inside the vehicle a lot. I do not believe you need as much as people think, although 1 box was not sufficient to do a complete large car inside (Doors, floor, boot, roof etc)Pieces are very large at 32 inches long, I think I would have been better off cutting them into smaller ones, as you can get yourself into a dire situation when its massive and its all sticking to everything including limbs and you are trying to fight it to make it fit correctly.Tended to feel that all the photos online of installations make it look super tidy and easy, and my install was more like a Mcdonald's burger, it never ends up looking like the photo. I could not decide if its better to try and measure and pre-cut templates, or just cut as you go along. Definitely found it more fiddly than I expected.

Good product it does make a difference to my car easy yo apply and cut

I needed to cure noise, vibration and harshness (NVH) issues with my car, and this stuff has exceeded my expectations. One trick worth knowing is to paint the surface(s) you want it to adhere to with a "high-tack" bitumen primer, available from most DIY outlets. This ensures that the Dynamat makes the best contact with the panels you're insulating. Cant' recommend this stuff highly enough - it's not cheap, but then quality usually isn't, is it?

Now my Bose sound system car sounds like it should! Also, made the car a whole lot quieter and feels more refined, particularly on motorways.
