dynamat
 

Has anyone ever used Dynamat original or Extreme? I want to use it on my floors, from the front to rear seats to quiet down my mufflers w/turndown pipes. Should I use the Original or Extreme? Thanks

I am honestly not sure how much this will quiet down the noise. Dynomat is designed to reduce acoustic vibration and secondary resonation. It might deaden the sound from underneath to a degree but don't expect for your car all of a sudden to feel like a limo inside. http://www.mustangworks.com/msgboard/biggrin.gif

Well, it may not be a limo but it still hauls azz! Since it's hard to hold conversations with people, because of the noise, maybe I will just invest in some microphones that will plug in the cigarette lighter.j/k

That is a good question, Stanger. My mustang is pretty loud also, and is hard to hear anything in it. I bought new carpeting for it, but was hoping to install some kind of sound deadener when I installed it. If anyone else hears of anything like this, let us know.
