Just a followup to complete this post:
After some weeks of drviing around locally, I have been hearing more rattles from the front cat area - like rocks in a sheetmetal box - and a reduction in performance. I can hear the S/C working most of the time though I am able to run at freeway speeds. The 80 feels like a slug, working hard. The rattle is always there as I accelerate, disappears at a certain rpm, and then reappers during de-acceleration. Classic vibrational resonance.
I think more of the front cat has come loose and plugged more of the passages. I guess its time to find a replacement cat...
