Although I enjoy driving my DeLorean more than anything I can't stand the noise in the passenger compartment. I've gone so far as to completely rip out all of the carpet and put down new 1/4" layer of closed cell sponge rubber and new carpet padding. This made a vast improvement on the road nose but the engine noise is still unbearable. What other noise abatement controls have other owners done to reduce passenger compartment noise?
