I haven't used the peel and stick although I have some. I was going to use on the inside of my doors. It's suppose to take away some of the tinnie sound. I did use Reflectex on the inside of the
cab and plan to cover floor with Peel and Seal then carpet padding/carpet. Extending exhaust to rear of truck should quiet down also. I believe some suppliers sell a jute firewall mat with a rubber backing also. Have fun and good luck.
