this is the muffler that comes with the heater
the muffler has an option in size between 22 and 24mm. I took a measure but still cannot tell. generally is the exhaust pipe 22 or 24mm in these heaters?
I remember people say it leaks. Upon inspection, i saw the exhaust passage is along the center pipe that has some fiber on its inside wall. does this pipe have a porous wall so the exhaust will leak through the crevice as shown below?
this muffler is a flow-through type rather than a baffled type. Flow-through style is recommended in John McK 47's videos for the lower restriction on the exhaust flow.
