Is there any way I can kill exhaust drone by lining the trunk with dynamat? Or is there another area I need to sound proof to reduce or eliminate exhaust drone?

 

I lined my trunk and rear seat area with Dynamat a few years ago and it makes a nice difference. The drone is still there but no where near as annoying anymore. The only negative thing about it is that even my LTs are quieter inside then most of the guys that I know.

I am running Kooks LT with the Ford Racing Stinger (Borla) exhaust as an FYI.
