I’ve put about $600 in sound dampening in the car including the dynamat style noico resonance damper, foam noise and heat barriers and mass vinyl.

Fun fact: my trunk carpet is the same material used in x3/x4 wheel arches. My former employer made them and we had a roll of pp carpet that had no center core and couldn’t be loaded in the press so I was able to take some for the project.
