Operation Temp at EGT 4 and 5

[diablo82]

I pulled all 5 EGT temp on my CTS2 screen and found out that the temperature at EGT4 and EGT5 is very much constantly holding around 550 and always higher than the rest of the EGT (1, 2, and 3). Is this normal? I just found this out couple days ago at highway and not pulling any weight. I did painted the very last section of the exhaust with high temp paint but no way it would have anything to do with EGT temp I am sure.
Any input would be appreciated.
