So here is what I figured created the main vibration.
The upper torque rods died which allowed the engine to rock forward and backwards softening the rubber hangers which hold the cat at the flex pipe. The softened rubbers allowed the exhaust to move downward enough to intermittently hit the cross brace between the cat and resonator. Even with the new torque rods plus all the new mounts I didn't need to change the flexie hangers allowed too much movement.
I didn't have any new hangers so I bent the cat support slightly downward which tightened the hangers. Vibration gone. New cat time soon as the head pipe cracked when I bent it. I brazed that closed but the metal is pretty thin.
thanks all.
