One exhaust more blue than other



Hey guys, 


Has anybody found their headers varying in bluing? Indicates one cylinder running hotter than the other.  You can see in the photo that the right header is quite blue whereas the left one doesn't have much at all. 

Wondering if it's something I should call the dealer about to check out the fueling is good. About 2.5k on it, had the first service done.

I have the ecu mapped from 2wheel and the fuel ratio seems perfect do you have a different pipe on?

I have leo vince header with cat gone pipes haven't even tried to discolour yet 

You would think they would both be getting same air/fuel ratio wouldn't ya 

Sorry not alot of help but have also seen pipes with a tonne more blue then that  not sure if a shop would map or change ratios ?
