Just wanted to share a few pics at the end of this thread. I shipped out the old catalytic converter to a recycling company and I cut it apart to reduce shipping cost which allowed me to take a look at the catalytic element. The honeycomb is seriously damaged, but surprisingly on the output side, and hence the rattle. I'm not sure what can cause this - some detonation? Or just aging? Interestingly, it was still doing its job, has never thrown a code, although the post-cat O2 sensor signal was not as flat as the same on the other bank..
