muffler temperature

[jasonh]

Anybody know about how hot the HT mufflers get in the stock location? I have a couple ideas floating around in my head....

Hot enough to burn the paint to a fine grey for the first 6". after that they cool pretty quickly.

well that doesn't give me a lot of info

under 700 degrees maybe? (I hope)

Exhaust for a two stroke is 1000 to 1200 max Cruise is around 1050-1100 as far as I have ever seen.

By the time the exhaust gas reaches the oprt and starts out of the exhaust, figure it has lost a coupe, hundred degrees. so 800 right at the header flange would be a safe guess.

What are we working on?

Not working on anything yet, but I'm kicking the idea around in my head.

Something to do with fiberglass, and it's not packing for the muffler
