You should easily be able to find an end cap from someone (this end cap is used on thousands of termi pipes) - don't go for a muffler as you'll pay a lot more.
What's weird is that the end cap is usually riveted *and* silicone glued into place! How could that have come loose?
Also note that since the end cap is off and you'll have to get it repaired, being at 18k you might want to look into re-packing it.
