BD 125-11 Ninja clone muffler fell off during ride!

[durtyrice]

Hello friends,

I was on a nice ride and my muffler fell off.

Anywho, I had to take two screw nuts from the fairings and hand tighten the exhaust to the engine. Luckily, this held for a few miles until I made it home

My question is - is the process simply put muffler back in engine then tighten the nuts? Or am I missing a gasket? If so, can you hook me up with a link where I can buy? I'm based in the U.S

I'm thinking I'm missing something because there's a decent gap between the engine itself and the bolt/nut. I took a picture. Thanks for the help!
