Bathroom fan vent duct

Bathroom fan vent duct
I just finished installing 4" rigid pipe for the dryer vent to outside.
the current bathroom fan is a 6" pipe that just vents into the crawl space. Can I use plastic flex duct and reduce it to 3"? What is the cheapest code compliant way for bathroom venting?
