I have a fumaze on my cars, an old aftermarket device that works great but they are getting hard to find and pricy. I have the firewall insulator in one of my cars and it works good but a bear to install.

In my opinion, the absolutely best device for reduction of noise and vibration is an over drive. You don't have to drive faster with an overdrive. The reduction of engine rpm makes all the difference.
