Vent cap blew off roof ... where does it go?

After a wind storm I found this vent cover on our deck. It could be from our roof or a neighbor's. The top of the vent cover says "AIR-JET Type B Gas Vent JC Jet Cap ..."

I've attached pictures of the vent cover and a section of our roof with lots of vents which might be missing this cap. Can anyone tell if one of the pipes in the picture is missing this vent cap?

It goes on top of your chimney. The only pipe that big that is missing a cap. Sewer vents don't need caps and they aren't 6" pipe.

Looks like it came off that tallest vent.

Sorry guys. You basically hijacked this thread with the discussion of venting systems. Not cool.
