Thanks guys! A little up date, Last night, I did a compression test (and I won't disclose my actual readings, I suspect the gauge is bad) but they were all very close. I ran the test 3 times and got almost identical readings. The engine runs too good for the low readings to have been accurate.
While inspecting the exhaust system, I found that the manifold clamp bolts (2) were a little loose so I tightened them and I went underneath and looked at the clamp. It was tight! I made a rubber washer out of an old inner tube and put it between the frame and the clamp. Then I took an old rubber pad from a motor mount and cut a strip off of it and forced it in between the pipe and the clamp and tightened it. I took the car out for a ride (not on an interstate) and while it's still a little noisy, there is a definite improvement. I would have not thought of the tailpipe transmitting all that vibration.
