Does anyone know the approximate temperature of our exhausts?

I'd like to see someone test the temp immediately after riding 75, then after coming down to idle for a minute or so, then do it again but shut the bike off immediately after the 75 run and see what the temp is after the same amount of time as the first test.

Also, I read one time that IR guns are more consistent when the spot where getting the reading  from is not reflective.

Heres my numbers. 
240 at the head
180 at the bends
220 at the baffles
These are off the heat shields.
Numbers from the actual pipe.
Rear head pipe 385
Front head pipe (as close as I could get to it) 280.
These were taken less than a minute after turning off engine after about ten minute ride in town. The temperature is low 50's with low humidity,  I would imagine they numbrrs will be higher with higher ambient air temps. A side note, both cylinder head temps were at 174. That was the highest temp I could find on either head. They are both pretty close in temp.

So are you gonna let the cat out of the bag or just keep us all wondering?  Cuz I am now thinking Project, Exhaust heat... 

Not yet.  Going to try some things out first.

Or maybe:   http://youtu.be/s3uc35AB1YY

I would love to, but with the Swepts pointing toward the ground I see that as a very bad idea.  Plus I don't need the police showing me that much attention.

There has to be some other factors. Riding last month in 35 degree weather at highway speed (well, my highway speed), I realized the front cylinder was and header pipe was experiencing probably a minus 30 degree wind chill, and the much less. So, depending on how fast you stopped to get the reading, there could be more variables. I think the exhaust could be hotter than "the engine" because the exhaust was just exploding/burning and the admittedly sharp curve of the pipe is going have more dwell time of heat passing over it than a flat surface. Just my thoughts.

What I was really wondering on the bike in that cold weather is what is harder on the bike: is the bike hotter at 80 mph at 35 degrees  (if, of course, one could find a legal place to drive that speed) or 60 mph and 90 degrees?
