hello,
guys need help, what materials that are good in insulating road noise?
planning to put something uder the carpet to prevent noise from getting inside the cabin...

I have tried sound deadeners but you can still hear road noise... and its very expensive is there other alternative materials? DIY hopefully

you can use the factory tar that they use... or dyna mat either way it'll add weight

its hard to get rid of road noise and it not either add a shitload of weight, or cost a shitload of money. buy a bmw haha. but its hard good luck.

I used Dynamat Extreme and Extremeliner. Pricey, but well worth it to me

Extremeliner provides maximum low-frequency attenuation and heat resistance. Extremeliner is a four-part composite barrier consisting of 1/8 inch layer of neoprene, 15 mils of acoustic lead barrier, 1/4 inch layer of high efficiency acoustic foam and a 3 mil urethane top facing. Extremeliner works anywhere on your vehicle's floor and firewall for the ultimate barrier from road noise and engine noise. Great for high heat areas.



NOTE: Extremeliner provides maximum control when applied over Dynamat Xtreme.

dyna mat would be the way to go. as long as u dont care about adding the extra wieght
