Thanks everyone, I think I have found the answer in another forum on here.

You put (2) spring washers together on each header bolt? Why?

As mentioned before, you can't do that with stock mufflers.

+1
I had a muffler that wouldn't stay on and I used the ultra copper on the threads and also in place of a gasket. Also make a support bracket from the muffler to the engine mount. I have used this on the bolt threads ever since and have never had a problem with a loose muffler since.

Sorry i meant 2 in total 1 on each bolt. The readon for using spring washers on exhausts is to alow for expansion and retraction as it gets hot and cools down always keeps the bolt tight, I used to use them all the time on my drag car exhausts and now i use them on my model engines gassers and nitro never had them come loose that way.

All kinds of good advice, but I have never had good luck with any perma-bond. Clean the holes and screws with carb cleaner like mentioned before. Get some Hondabond HT, apply to the screws and muffler with no gaskets. Let it sit for about a minute before you tighten it down. Also make sure you have a strap on your muffler. I have never had a bolt come loose or a leak develop using Hondabond, it is by far the best stuff I have ever used!
