Anyone use DYNAMATT to reduce road and exhaust noise?

NewlyIMPORTed · 03-30-2010, 12:24 PM

doing just the the whole trunk area will help a lot with road noise

thats what im thinking just the trunk area. because all the noise is coming from the rear anyway? so no one on the forum has done the dynamat?

I used dymamat extreme on everything from the seats back. I originally wanted to eliminate some rattles that showed up after after the exhaust install and get rid of the racket that takes place after driving over a bit of loose asphalt. All in all it worked out beautifully all rattles are gone and the rocks pinging the wheelwells is greatly reduced. Cruising on the highway theres much less road noise I think after I do the doors and a few areas up front ill be at luxury status. Also of coarse the bose sub in the spare thumps just a little bit harder though I dont use it much due to exhaust note addiction.

It will be a pain as you would probably have to take the front seats out to get under the carpet. I plan on doing the front floors last if at all.

so its noticably quite with just the rear hatch section? Im concerned with the road noise and also it would be nice to have less exhaust drone in the cockpit as well. thanks

yes its definitly much quieter its hard for me to tell because the exhaust is loud but I can hear very little road noise over the exhaust. At about 70mph around 2.5k rpm in 6th everything have gotten alot quieter including the exhaust. A good example is befor I did it when driving in the rain I could hear the water spraying constantly in the wheelwells now I dont hear anything.
