Customer Reviews

Rated 5 out of 5 by from performs as advertized This is the second time I have bought this product. I put it on the back side of the engine cover on my Arctic Cat Prowler. It was a very hard job to do but it was worth it. It made a big difference in heat and sound. My Daughter's Husband has one so that is where this going after he seen the difference it made in mine. It is true that it is not the easiest product in the world to work with but take your time and it will come out good. In tough places make a pattern and that will help a lot. I put foil tape over the seams and if nothing else it made it look a lot better.

Rated 2 out of 5 by from Boom Mat foam Nice product and light weight. Difficult to make a smooth cut even with the sharpest blade and a curve is harder. Doesn't flow out well on compound curves.

Questions & Answers

What is the amount of db that this material reduces? Your 1/4” product lists the temp reduction and the db reduction. What would the distance that this would have to be kept from an exhaust manifold?

Asked by: 05chummins
Unfortunately, the manufacturer can not provide a DB Reduction. They do not have one that they use as a marketing claim. It is rated for temperatures up to 275 degrees F so a foot distance is roughly what we would recommend.

Can this be used to replace the factory pad on underside of vehicle 

Asked by: Welshie
This is designed for under the hood. It has not been tested with the weight of foot traffic that an underlying factory pad would have. We would however, recommend our Xmat Item #15841 https://www.eastwood.com/xmat-sound-deadening-18x32-ines-34-8-sq-ft.html

Could this be used in wheel wells? Behind the plastic fenders? Would the adhesive withstand any moisture and spray kicked up by the wheels?

Asked by: DarekM
This is not recommended in that area due to the moisture being able to get to the adhesive backing.
