Could someone tell me what coating or treatment is applied to the stock headers? I love the look. Also, what would be a safe polish/cleaner to use on them to keep them looking sharp?
I think it is just highly polished stainless. No completely sure, but that's what it looks like to me. If that is the case, the regular pipe polish/blue remover should be all that's ever necessary. I'd keep it too a minimum, whatever you use, it will eventually cause microscopic scratches, and that will just attract crud. Whatever it is, mud doesn't stick to it right now.
