For sure. Thanks.

I had that in the back of my mind, but had this notion that the
exhaust had to be hard mounted to the engine and that the flex bellow
would eliminate the vibrations. Ha! --- :^)

Thankfully the engine hasn't emitted too much vibration, but isolating
the exhaust from engine vibrations is the thing to do..... for now.

Cheers,

Neil.
