I would recommend the FMF Universal Spark Arrestor instead of the DG muffler.
The FMF silencer is less expensive, and will be easy to install on your Zongshen 200GY-2.

You can buy a stainless steel, XT225 exhaust header
and the FMF silencer for less than the $200 DG muffler, and I'm sure the installation will be
much easier.
