Two rear head pipes!

[max03]

My two rear header pipes are blue, not sure it its due to it being to lean? Or if its common for the two rear cylinders to run warmer due to less air flow. My setup is holeshot 4into2, k/n filter, shim under stock needles, 150 main jet. Any suggestions would be great, Thank You

It is normal phenomena for chrommed steel. Chrome - blue, stainless - brown/yellow.

You may have some temperature difference beteween front and rear pipes which is nothing
unusual but, if you are still concerned take a laser gun temp meter and messure each pipe at
cylinder outlet and share the results.

Almost every vmax I have seen w/ aftermarket pipes the rear pipes discolor because they get hotter I am told less air to them .

The other thing is the front pipes are double-skinned, I don't think the rear are?
