my exhaust is getting a gold color right where header pipe goes into muffler? all is stock carb and exhaust , i have heard of blueing up on header pipe but gold. any help, thanks

I thought it went from chrome -> gold -> blue

It's not that I don't like the color, I use it as a way to tell how the engine is running.  Is it just the material the header is made out of or is the engine running hot?

The way I saw it, my exhaust should be gold then blue.  Kinda like how a marshmellow gets a nice golden brown then it gets darker until it's black.

My upper header too has developed a golden hue ... and most of my Riding is around town, stop n' go stuff.

 Yeah!  Wear your colored pipe as a badge of honor.
 It's really only because the double walls of the savage pipe are not that far apart, so the engine heat transfers to the outer pipe and colors it.  If you live in hot climates or ride in widely varied temps or elevations, it will be more extreme and happen faster.  BMW and Moto Guzzi riders pride themselves on the blue of their pipes!
  Bikes that don't blue have double walls that are much more separated, if you could see the inner pipe of these bikes they would be blued.  You really have to baby a savage to not get discoloring on the pipe.  Enjoy it, bikers will respect you for it.
 Pipes will go golden, then blue, dark,dark purple to almost mirror black.  You can watch it happen in seconds with a blowtorch on chrome.

Mine is gold all the way down to the end of the heat shield. All highway miles at speed.

My understanding is less spacer = richer.
