This "muffler"? Is rattling. But I can't figure out what this part of the downpipe is. I know the two cats are above it. I can't seem to find a diagram stating what it is.

Is it another muffler? Or a resonator?

I think that's the big, stainless, flex joint thar bolts to the ball flange. I don't think it's replaceable.

Downstream Catalytic converter. If it's rattling it's done and must be replaced.
