sapper_daddy Posted January 31, 2006 Share Posted January 31, 2006 Just starting another little thread about a general application......... I've used sound deadening material for a few applications on other vehicles but normally they are so loud it doesn't really do a whole lot for it, I've seen a few LS with sound deadening, of course i'm sure every one has seen the Lexls one! So the two main choices here would be Dynamat Xtreme or the Fat Mat i see on ebay which that stuff doesn't look too bad either because it's 40 mils and you can get and enourmous amount for 100. What i want to know is what works good, how well does it work in a LS, and what are some personal preferences and experiences. I'm not sure if this is a very common upgrade, as LS is very quiet to start with, but for curiousity sake i wanted to enquire. Thanks and i hope this stirs some good conversation.

monarch Posted February 1, 2006 Share Posted February 1, 2006 So the two main choices here would be Dynamat Xtreme or the Fat Mat. What i want to know is what works good, how well does it work in a LS, and what are some personal preferences and experiences. My experience has been that Dynamat Xtreme type products are vibration dampers, not sound absorbers or sound barriers. Since a Lexus already is already extensively vibration damped, products like Dynamat Xtreme do not cut down much on interior noise levels. I believe the most prominent noise in a Toyota/Lexus is road noise and traffic noise it needs to be attacked with sound absorbing materials like fiberglass, 3M thinsulate, jute padding or accoustical foam and sound barrier materials like loaded vinyl mats or asphalt impregnated jute padding. You either have to spend $500+ on these types of products from commercial sources or visit auto wrecking yards and take them out of existing luxury cars and passenger vans.
