Where is it located, exterior wall access where you could punch through? What part of the world are you in? Fart fans are not made for static pressure so when you shove a bunch of air into a small 3in duct it can't push it. It would be best to have a decent fan and 4in duct but if that's not possible downsize the fan. What fan did you install? What size is the bathroom?

Bathroom is located in a corner on the main level of a two level house. It has close access to 2 exterior walls that could potentially be vented through. That would be a good option and I would just not use the existing ducting.

I’m in the Pacific Northwest, in Vancouver.

It’s a Panasonic one with options for 50-80-100 cfm. Bathroom isn’t very big, about 50 sq. Ft.
