It is possible your motor will not overheat while at the same time your exhaust may not be getting enough water thru it to cool the pipe. I have had the same problem. It turned out I was running 50 degrees hotter than normal. Infrared temp gun is handy here. Not to be an alarmist but this could be a dangerous situation if you don't check it. The quick check is your hand. You should be able to put your hand on the exhaust.

Best peace of mind is to replace them.
