Exhaust - Inspect & Polish

Early into the project the wheels and exhaust came off for some insights as to the pitting and/or corrosion present, and a sense of what effort would be required to clean and polish them up.
The exhaust appeared fairly bad, but also covered in a thick film of oil.  Using Marvel Mystery Oil as well as Blue Magic metal polish, they actually came out very well.  I also used the cola and aluminum foil method, which seemed to make a difference.

A couple of 'before' images above, including the original warning label, which I'd like to try to keep intact.  Partway through the polishing below:

A next-to final image of both exhaust sides when nearly finished; poor lighting here, but not a bad result.  The cross-over pipe will need some work, but is not as visible.  New exhaust clamps in chrome were purchased to finish off the assembly.  I also plan to fabricate new brackets to hang the pipes from the passenger peg bracket.

Side note, the exhaust headers were wrapped in pipe tape and safety wire; this allowed moisture to remain in contact with the pipes for extended periods, and when the wrapping was removed this proved to be the case.  Some polish will help quite a bit, but that will have to wait.  Worst case, I think that black paint on the headers will fit into the overall approach for the project.  I would rather keep them shiny, however.
