I pulled my headers off last night because they have gotten pretty dirty over the years and I'd like to get them back to their original stainless steel color. I have Termi high pipes on the bike and attempted to clean the S-pipe that go to the cans last summer. THey looked great after scrubbing them with a 3M scouring pad and some WD-40, but they got some slight surface rust some after from moisture in the air. They never did that before so i wonder if there's some coating on the pipes from the factory that I took off. I don't want to have this happen on the headers as well, but also don't want them looking so dark/dirty. Anybody have some experience in cleaning the headers?
