Not sure about a muffler but I received some great suggestions a few weeks ago on this link: https://tw200forum.com/forum/general-...-big-guys.html
The TDub is great for hunting! I swear that game does not even hear me when riding & I see so much more when riding compared to the truck. The only thing I am hunting
now is dove but I ride right up to deer, turkey & have seen a ton of coyotes just on dirt roads and they don't spook as much when approaching. I just strap a soft a gun case next to my right leg strapped from rear seat
to the front of the gas tank on top of the plastic and it works great. I have used this position on a horse in the past and can unzip the back and get the gun out good and quick.
