I used Birchwood Casey rust and blue remover to eat the rust on mine. It's for guns but is pretty strong stuff. There's pits and all sorts once you get the rust lumps off so hit that with files and fine emery until it was flat enough to polish , then got cracking with the polishing mops and autosol for the hard to reach parts. They'll go yellow/gold again soon enough but I can keep on top of that.
It'll get thinner and thinner where stubborn rust has been removed so keep this in mind while you're working on them. A scraper will help loosen things if they won't budge.
It's not a high grade stainless on the systems, that's a cost thing. Once they're presentable they're a lot easier to keep looking good and they're definitely better than mild steel headers , chromed or not.
Another thing I haven't tried is spirits of salts, it's hydrochloric acid based (I think) so may not be the best stuff to be splashing around. It's gets corrosion off fast tho.
