wr426 exhaust problem

after starting my 2001 wr426, my header begins to glow red after about 30 seconds of ideling. Does anyone know if that normal or what is going on there. It remains normal while I am riding but when I stop it starts to glow agian. Please help with some advice or informative answers. Thanks a lot.

yes that is normal. if your jetting is stock then it is most likely quite lean.
