Default exhaust turning yellow

Hello all!

I have a 2005 c90 and the rear cylinder exhaust pipe is turning yellow at the header. The bike only has 5000 miles. I don''t over rev the engine however I shift a little over the the compagny spec. Is this normal and why is it only the rear cylinder?

Thanks
