Mitsubishi Pajero - Whats this pipe called?

[timph123]

My 1995 Pajero 2.8 TD burst a pipe recently following overheating. Can anyone help me identify what the pipe is called so that I can go about sourcing a replacement?

Thanks.

I have a Shogun V6 so not au fait with the diesels but a Haynes manual should be able to identify it?
