lean burning is what causes that ,,,,,cv stock carbs tend to burn lean if not right

Aftermarket pipes are often single wall and show blueing. Stock setup had double wall to keep it from showing. The only way to know if you're safe or not is to get a gas reading. Some places have an O2 sensor to stick in the end and give you a hint. I can't vouch for their accuracy.

For sure,Although... I have seen stock GL1100 mufflers that are blue, must be single walled on the muff part.

Like them, as they last almost forever, & work great. :smilie_happy: Or hate them cause they are big, not real sleek looking, & weigh a ton. :rant: They work, & do not usually turn blue, no stock ones i ever seen did :nea:
