Use black iron pipe from the Hardware store (DON'T use galvanized! Its toxic!!) and wrap it in thermal tape, sold here by our host.

Here's a link to the rebuild I did in stainless:

Its now in its 10th year with no leakage.
Thank you. It's most likely the time to install a brand new hot exhaust section. Seems to be not too complicated job except for unscrewing the old bolts that look rusty. I think I will have to take the manifold off and then work on the bolts.

When connecting the pipes and elbows what kind of sealer did you use? Obviously, plumbing tape won't work
