Hi Everyone - long time since I last posted (apologies)

Wondering if you knowledgable people know what material people use to make their own turbo oil feed pipe?

Referring to the one that bolts on to the side of the turbo - mine is currently covered in metal braid. Can find replacement for 100 quid but seen that they can be made. Not sure what material though as silicon wont take the heat/oil and metal wouldnt flex enough (would it)?

Thanks in advance!
