I bought a refurbished unit from Hinklin power, it came with the muffler. Actually when I bought the genset I was not going to use the muffler, so I told them not to send it. 3 months later I called and said I needed it, they sent it, all I had to pay was the freight!!!! I had to chop it up a bit and weld it back together but it works. You do not need to use the Honda remote, most universal ones will work. I checked the Honda bike mufflers, they are pricey.
