Mine stays mostly yellow and purple once it's cooled off, and blue clear to the can while it's running hard. That's how Ti is. The blue and the purple are my favorites. Stainless has a different color palette. :thumbsup:

Unfortunately, the bend in the header will eventually turn a dull gray/brown up to the "bomb".

One of the things that makes people think this is abnormal is that most MC exhaust systems on road and play bikes, and even off-road and MX bikes until recently, are usually steel, and finished somehow, like with paint or chrome, rather than left bare. The Japanese long ago started building double walled pipes for their road bikes so that the chrome wouldn't turn colors. It also hid the fact that the right size pipe for good performance was a lot smaller than the American public expected to see, but that's another thing.
