Headers temperature ?

Headers temperature ? (Ceramic Coating is done)

Hi all,

I am planning on doing a ceramic coating on my headers and exhaust. I believe I am going to have it done in black. Unfortunatly, after a black ceramic coating, the headers can go up to 900°C (1650°F) whereas it can go up to 1400°C (2550°F) if I have it done in white.
So I was wondering how hot the header can go on an XB9. Thanks !

exhaust header surface temps ALWAYS hotter than EGT(exhaust gas temp). so-called "tuners" say they like to see EGT of approx. 950-1050 degrees fahrenheit during fairly moderate engine loading for both sportsters and v-rods. this is measured center-of-pipe and 5 inches or so downstream from the exhaust port. NO reason buell XB temps should be much different. i can't think of a conventional riding or atmospheric scenario that would yield header temps even approaching what you listed. you should be fine with either color.

Black will be okay. https://en.wikipedia.org/wiki/Incandescence

Not done yet, actually, the headers and mufflers wills be shipped to the guy tomorrow. But I wanted to post some picture of how it looks like now :

Everything has been sanded. The muffler definitly looks better but needs to go to the boilermaker... And 150€ to add sadly... But it will look like a brand new one ! As a new muffler costs like 700€ in France. It is still a good deal !

I can't wait to see it finished !

Oh by the way, I forgot to mention that the headers seems not get as hot as they were before getting coated. That's cool !
