i would imagine that the muffler would be cooler than the engine, since it has more air flow and that it is not combusting fuel!

Temperature measurements I took while I was breaking in my Moki 180 on the bench consisted of:
1) Between the cylinder cooling fins
2) At the base of the glow plug
3) At the exhaust manifold where it is attached to the engine
4) At the surface and exhaust outlet of the muffler.
5) At the crankcase
The highest temperature I recorded was right at the exhaust manifold and this sometimes was well in excess of 325 F degrees. The next highest point was at the base of the glow plug. Then in between the cylinder cooling fins. The muffler temperature was always significantly lower than the other measurements with the exception of the crankcase. The crankcase temperature never came even close to the other measurements.

I would think that the exhaust would be hotter than the engine because of the amount of continiously flowing exhaust gasses. If your engine is getting so hot that it is flaming out, then consider riching your fuel mix up. Also if your using a tuned pipe the exhaust shold be hotter the closer you get to the head. Hope you got something useful out of this response.
