F430 EGT

I was wondering if anybody knows the normal exhaust temperatures for a stock F430. If not, I'll get out my infrared thermometer and go for a drive. I'm about to install AP headers and am getting them coated at Jet-Hot. To avoid the need for exhaust wrap or blankets, I am getting the ultra extreme coating (external), however I am also considering getting the extreme coating on the inside. They say the inside coating might not last if the exhaust gas temperatures go above 1250 degrees Fahrenheit.
