The stock mount allows for an acceptable amount of movement to reduce the vibrations felt in the cabin. This works in conjunction with the flex pipe that'* part of the exhaust. The stock mount is good for the purpose it was designed for, but most people can live with the slight vibrations created by the solid mount for the benefits it provides.
The problem I had was that my mount wasn't as tall as my original mount and when I tightened it down it put too much strain on the exhaust manifold and created a small leak.
Silver Bullet can disagree with me on this if he likes, I respect him and heartily thank him for the help he gave me when I did mine, but I haven't come up with another reasonable explanation (maybe my flex pipe isn't as flexible as it should be or the leak was already there and this just made it more noticeable) for why I developed the leak immediately after installing a mount that was smaller than the original.
Point is, I believe, as do many others, that a solid mount is a good thing. I will simply caution people to make an effort to create a solid mount that is approximately the same size as thier stock mount.
