Message	Just installed a Billy Boat exhaust system in my 91 NA Z. Works just fine but too much interior noise and drone even with my choice of "road" muffler. The system already has 2 resonators /pipe. I'm thinking of lining my trunk area with Damplifier Pro sound dampener sheets. Anyone out there use them and how were they on interior noise suppression?
