Got a better look--photo added. The question is now about the pipe that comes from the top of the part in the red circle and goes down beside the other pipe, with the two pipes joined by a metal spacer farther down to where each looks like it takes a rubber hose.
Does it go to the middle top of the catalytic converter or to the front end? The other pipe would then go to the other pipe.
The two pipes from the catalytic converter come forward to near those two other pipe ends. the two metal pipes coming forward also are joined along the way by metal spacers. They have bulb things on their ends that in turn, take rubber hoses.
One pipe from (the front) of the cat converter has the bulb thing as E8TE-9A487-AA which is "secondary air pump check valve" The other pipe has a similar/same bulb thing but can't read the number on it. I am wondering if both would be the same if only one of those pipes receives from the secondary air pump. Would that indicate which is which?
