There is one on each side.
Other than a cab to frame connector is there anything special about it?
Is there a spring in there for a "floating cab"?

That is the holder for the muffler bearings.

Silencer to reduce noise, on former GM models they had them on air intakes.

most weird "appendages" on intakes or exhaust are for tuning it. this one probably absorbs a nasty tone.
