well been looking at the stuff for a while now for anyone who doesnt know it basicly is a noise insulator used for eliminating rattles and it helps kill road noise, working for best buy i can get it a a significant discount and im wondering if that kills the exhaust tone that you get inside the car especially with aftermarket exhaust. also if anyone has done this did it add alot of weight to your car....am i wasting money if i do it??thanks!

I used a cheaper version from a company here in Texas when I swaped put my interior and it helps a lot. Doesnt way but a couple pounds at the most and helps with heat as well. I used 3M spray adhesive to lay it down.

i have fat mat in my car (check my gallery for pics) i did it for my JL but it did make the reqular road noise go away and when you roll the windows up you could tell you put it in. plus my car pounds and it sounds alot cleaner outside especially helped my hatch rattle. but... if you do your whole car you will add 15-20 pounds of "non go fast" weight.

Don't use dynamat, its expensive and not the best out there. Peel and Seal is half the price and insulates even better.

with your discount we might be talkin about a whole different story, but when i did it, it wasnt worth the aggrevation.

I worked in a car stereo shop for 4 years.

Since then, alot of companies have come out with their own product to compete with dynamat. They're all ABOUT the same with some slight variances between them. I would shoot for a foil-backed product no matter what you get, as they seem to work better than others.

Additionally, I would line the backside of the tail light buckets, and the back of your license plate with the product, to help insulate from sound as best you can. Alot of the sound you get is actually resonance (vibration) of other parts of your car. You can also buy sound insulating undercoat and do the underside of your car, although I wouldn't do directly by the end of the exhaust, you could do the floorpans...

If you're only going to lay something under the carpet, I always use the cheap jute stuff from JC Whitney. You can't see it once installed and it does the same exact thing. Dynamat is great, but too expensive, in my opinion
