Surely you can get the correct one from the US?

If you use any kind of sealing paste in those fine threads you may come to regret it. In my MAR, I use the copper ring from In Motion which seals fine. If the ring starts to undo itself, wire it to prevent it.

I ended up going to an automotive supply store and buying an exhaust gasket (crushable metal type) for $2.50. When I got home I found out it was slightly too large in diameter to fit into the cylinder so I cut about 1/4" out of the ring and it easily bent into a smaller diameter to fit into the recess in the cylinder.

Fired the bike up for the first time today, sounded good and no exhaust leaks. I did use anti-seize on the threads and noticed the retention ring did loosen a bit after a couple of minutes of running. I'll keep an eye on it and safety wire if required.

Thanks for the tips everyone!
