That sounds like the catalytic converter shield.

Typically it'* welded on to begin with and over time and heat cycles it rusts at the welds. I have seen and done this many times. You head over to Home Depot/Lowes and into the plumbing section. They have super large metal clamps. (like for a radiator hose..but much larger). Get 1 or 2, go around the cat and shield. No more worries.

its below the down pipe, i can see it from the engine bay..
it sounds like the metal clamp idea will do the job.
thanks..
