FF is correct as usual,
I agree. And I personally have a stone to uncover on Willy in that regard. Willy has a tall exhaust riser connected to a FG lift muffler via a very stiff exhaust hose. I haven't brought it to the fore yet as I have little vibration and so many other priorities.

Anyway the engine vibration will be greatest on the attached parts furthest away from the center of rotational/torsional vibration. The attach point of the hose is such a point but can hardly move. I think I need to attach a flexible short pipe (accordion) of SS to allow the engine to move.

And of course there is that possibility that that rigid hose is keeping the engine from moving and reducing vibration. But one would think that would just transfer the vibration to the lift muffler or what it is mounted to.

My engine mounts are fairly rigid. Polly Flex plastic. So this thread is a reminder to get w the yard guys and "get-er-done".
