Review on Noico 80 mil 10 sqft Car Sound Deadening Mat: Premium Butyl Automotive Sound Deadener for Ultimate Audio Noise Insulation and Dampening by Dee Holt

I have a non-original exhaust system on my Infiniti G37 Sedan. And the roar really annoyed me, but I didn't want to change the exhaust because I liked the sound. So I bought 3 packs of these, removed the spare wheel and padding from the trunk, completely covered the trunk with this stuff and put it under the back seats. To be honest I didn't think it would help much. Well I was wrong. I got in the car and started moving, and the drone was cut in half. It changed the world! It made it so quiet I didn't even think about it. Now I can be happy with the sound of my exhaust and have no droning nearby. If you're looking at this to reduce exhaust noise, it's worth buying. It really works! Thank you!
