That is where the Secondary Air Pump mounts to.
It is an emissions devise that typically starts on Cold starts, runs for approximately 90 seconds to reduce emissions on a cold start.
I would be surprised there is no CEL. I think there is a CEL for a malfunction
I don't think not having it would effect engine performance
