Air intake routing?

Hi! I'm looking into servicing my bus and when I got around to change air filter I noticed that one inlet hole isn't connected to anything (see green  ring on image)! Where should this go?

should be a flexi connecting to the other end of the heat exchanger jacket on number 1 exhaust pipe like the one in front of it

Thanks! I took a look underneath the engine and found out that the part the other flexi is connected to (green arrow) have been rusted away, yikes! Do you know what that part, hugging the exhaust pipe, is called? I've been browsing justkampers and brickwerks but can't seem to find anything that do match.

You wrote "other end of the heat exchanger jacket" - would that be where the yellow arrow does point at, at the same pipe as the other?

yes that's right your air intake warmer jacket is missing from the exhaust pipe, rotted and taken off probably because it was making a noise

this what it should look like exhaust

Aah I see, I was looking for some part to just attach to the pipe, no wonder I couldn't find anything. I might replace that exhaust pipe then. Thank you so much for the helping out!
