Good advice Lynn. Here is a bit more info while we are on the subject.
Ed Anderson is using .140 thick SS pipe bends designed for cheap SS hand

rails

and it does'nt even discolor. A bit heavy. You can buy it from RB Wagner.
Ideal to build your own turbo manifolds. I would only use it for the
first couple of feet and then go down on the wall to .065 and finally
.035 out on the cooler ends. Slips joints on all transitions.
A system like this should last forever.

Paul,
How does 316 SS go for exhaust.

Supposedly not as good as 321 but it sure works for Ed in the .140
thickness.
