    Just wondering what causes the exhaust headers to discolor to a blue color? Is this a sign of jetting issues, or is that normal when they have gotten hot?:excuseme:

    Have a look at your headers at night-they glow red. The blueing is a good sign-nothing to worry about.

    So is mine and I have found that if you buff the head pipes to a nice bright polished look that you will have less blueing and they are easier to clean cooked on mud and stuff off.
