Newly joined this group but have been enjoying reading about your projects @Frame Maker ! I have a 77RD400 I’ve been puttering about with and I have a question about what you do with the expansion chambers on your pipes? I have a set of unpainted Spec II pipes that I’d like to keep “natural” like the pipes on the first photo in this thread. Are they ceramic coated or oil finish?
