Default 07 silverado 5.3 exhaust WTF

I just got my truck saturday, 07 NNBS RCSB 5.3 and I was looking under it today and found this piece. Is the some kind of 3rd cat?

Driver side look toward passenger side


directly under passenger looking up

how well can those flex? that may be just what i need to finish my exhaust.

Can they hold a bend? or are they just to reduce vidbration?

It also lets the engine move under load without putting stress on the exhaust.
