Its Pretty normal because the walls of the header are so thin and i took mine off to see how thin it really is. take a look for yourself and you will find out why too.

If you are glowing Red then that means your quad is too lean and you could do engine damage. Glowing orange is what the quads should glow. I am pretty sure though if you are glowing red that is too lean...anyone else want to back this up or am I wrong? If it is seriously red then you need to re jet.

My two YFZ450's headers glow , my friends YFZ's glow, as does my neighbors YFZ's.

It's normal, it's OK.
Glowing is normal, as long as it is glowing Red. Glowing orange is norma,l not red, red is too lean.

GLowing on this engine is normal. Pipe wall thickness is to blame. Mine glowed when it was so rich I could smell gas out the tailpipe.

Its quite normal. My Hayabusa has a Titanium system and at night rollin slow it does the same thing.
There is quite the amount of heat from the internal combustion engine.
