This is a common header design for he SL-C. Has anyone had success wrapping them? The intial curve below the flange makes it very difficult. Anyone have images of how they insulated them to mitigate heat?

Can a bundle of snake exhaust system be welded up using the long 4 port header flange? Or do I need to use the separated single flange per tube?
