Need help identifying!!
2004 F-150 5.4L V8- Can someone please identify what letters A and B are in the picture? I believe that A is the catalytic converters and B are the resonators but I want to be sure. Thanks!

Just a guess, but seeing that they are all shielded, I would think that they are all cats. A resonator, if equipped, would likely be mounted behind the Y-pipe.

I don't know where you are located, but if you are in a corrosive area, the shields might have corroded and fallen off or been removed because of rattling.
