Wedge some blocks of wood cut into angled pieces and wedge them between your pipes and the floor or frame use about 3 per side that should take any exhaust noise out then remove them 1x1 to isolate the problem and it may be as simple as the hanger you changed
Will do !
In the meantime I took it out for another test drive and checked a few things.
It seems that the vibration/rumble comes and goes between 2500 and 3200. Above 3200 it seems to be gone.
It idle the exhaust tips seem to shake a lot. They don’t seem to be firmly located.
I popped under the car and checked the hangers.
The look pretty flimsy to me. Maybe it worked for a very mild 350.... but not so much for a high performance V8 ?
I will need to measure the exhaust pipes again but to me they look closer to 2 than 2.5 inches.
