You could use a perfect size muffler clamp to match your bikes tubing. Custom bend some flat stock band steel
wrap around the muffler to reach the muffler clamp.
You could even tack weld part of this fastening arrangement to the muffler. Thing is all of this is a matched effort . The motor will need to be mounted solid. You could slot your holes in the muffler clamp down to muffler pipe junction set up a little.
Most all of these kits come with a little band clap for the muffler to fasten to the down tube. Granted it is a cheesy one it still can make a difference are you using it?
