Reason being, I was using the Red Permatex, and I don't think it held up. I switched to the copper stuff and it seems to be doing much better. But I also ended up with a better clamping solution.

looking to see if it is <500F

The temp at the header where it joins the cylinder will be in excess of 1200 degrees when under full load. At night you might see it glowing. Steel glows cherry red in bright light at 1300-1400 degrees.

The temp at the header/muffler joint will be maybe 450-550 degrees less than this. During a relaxed cruise, say, 50 mph on a level road on an 80 degree day, the temp might be in the neighborhood of your 500 degrees, but occasionally it will be higher.

I will end the debate next time i ride - I will take my temp gun with me and check it mid ride (while stopped at a light of course) and post actual findings for all who are fighting the header/muffler seal/shift pops problem......and cant squeeze the pee out of the connection enough with a clamp or goo the joint with cooper rtv or jb wld or muffler patch or whatever and dont own a welder to seal it shut.......i just want it to quit stop shift popping, dad-gum-it!

When you slow to a stop, the temp at the joint will decrease very rapidly. It will not give an accurate reading for what is happening to the joint while at 60mph, for example.

Maybe you could train someone on how to use your temp gun, take them for a ride, and have them get the temp while you are at speed.

Although I imagine it could vary a little from bike to bike, based on the exhaust adapter, the muffler and the carb jetting.

There ya go for all those not so "direct fits" out there,.........

and the answer is on my 1996 with DEI Titanium header wrap:

652F At the head
465F at the joint
385F Muffler

after my normal 45-50 mph ride about 15 miles while idling - same numbers when i got home +/- <5F idling after 30 mile ride @ < 50mph

Those numbers are considerably cooler than when you were at speed.
