The ends are metal spinning. The brackets and deflectors are laser cut duplicates of originals.
The centre pipe is standard T exhaust pipe, but the first two inches is expanded so the original pipe will slide into it. This creates a shoulder, up to which the front end spinning wedges.
I was given the stainless steel sheet from which the inner baffle and the outer shell were rolled. A mate runs a heating/cooling business and rolled the shells for me, with the correct double fold seams.
It seems a pity to paint them but making the ends in stainless is not on my agenda.
