***** Good idea about the flexi connection.
But, you are addressing the exhaust flange donuts and my problem is with the
suspension rubber donuts toward the rear of the exhaust system.

Do the engine mounts affect the rubber donuts? Too much engine rotation
causes the exhaust system to twist too much?

How do you test/examine the suspension mounts to see if they are
