I saw one new at a gas station before I knew about the rubber mounts and even then it shook. It was jumping around so bad I yelled to the guy that his exhaust was falling off. He called me over and showed me the whole engine was jumping around just as bad due to the rubber mounts.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
