I've tried just about everything to keep my right exhaust post from coming loose. even after using lock washers that clip onto them they loosen while riding. Any suggestion? Is there such a thing as high heat lock tight? If so has anyone tried it?

If the threads are in good condition, it should be possible to get them to stay tight. The lock washers simply stop them falling all the way out but allow the threads to "chatter" and destroy themselves.
If you suspect that your threads are not in good condition then you really need to get them sorted. My preference is for bronze inserts although tapping oversize and fitting oversized nuts can provide a quick in situ fix.
I would avoid Thread sealers as they may cause damage on removal and be dificult to clean out. I actually use copper grease on my threads to aid dismantling.
You will certainly need a good-fitting "C" wrench. After initially tightening the nuts, warm the motor up and then try again. They should move a little. If you're using new sealing washers, you may need to do this a couple of times until they are fully compressed.
I have seen owners tighten the nuts with the motor running. Perhaps the vibration allows the threads to go that extra fraction ?

The first thing you MUST have is the correct spanner wrench that is designed for tightening the exhaust nut. Provided the threads are in good shape use a 4 foot cheater pipe on the end of the spanner to get the needed torque to keep the nut tight. Believe it or not, that is how they did it at the factory.
I would also suggest you join the International Norton Owners Club and purchase a copy of the "Tech Digest". It contains all of the latest tips on how to fix and maintain your Norton.
