Wow... THats an extremely good price for it. Yes the kit from Dyamat is around $250 at local shops. I'm interested in Raammat. If it does as good as a job as dyamat I will purchase it. Plus I can double layer that stuff for more obsorbtion.
Normally Road noise is reduced 9-12. Even 18 db if your lucky. I believe that will be hard to get 18 db but I'm sure it'll stop most of the vibration and sound-proof the car more.
