Here is to further complicate the matter.......

If the engine is solid mounted to the frame, any amount of torqueing, moving, shifting is going to be along with the frame itself.

So the the pipes, the frame and the engine are all moving in unison, I can see how they would stay together. However when the engine itself is mounted on rubber engine mounts, the frame itself stays put, and the engine moves while the sidepipes are securely held together.
Is it safe to say, if the engine is hard mounted the sidepipes should be as well?
Or, if the engine is on rubber mounts so must the side pipes?
