I have been lookin at all these sound deadners and does anyone have any background info on fatmat. I mean it does the same thing as dynamat for half the cost. I see a kit on ebay for 99.99 for 100sq ft. Or 44 sqft for $49.99.

 

pretty much all the same....tar on aluminum foil.. you basically pay the difference for some extra letters (brandname)

 

there has to be somthing differ about fatmat and dynamat extreme.

 

me personally i use cascade since it is not tar based and does not give your car that tar smell...

 

This is true...for the first month or so, the tar/aluminum stuffs smell real bad. Dynamat extreme doesn't smell though (or may be doesn't smell much if any).

 

For an inexpensive alternative, try Peal N Seal. I got it at Lowe's and did the doors of my MDX. Works as good as all the others. I did the inner and out door skins and I did notice a big difference in road noise and some extended bass of the mids.
