hello, I have a 1937 ford coupe and before I did the inside with dynnamat, you could hardly hear anything. once I dynamatted the floor and firewall my wife and I could actually have a conversation while we were driving 70+ on the freeway. around town is great. I cant speak for it in the cobra, but in the street rod it is a must. I experienced the same thing in my 49 ford pickup. I highly recommend it. I do have a factory five and not sure if it has been sound deadened or not. Hope this helps.
