OK this is probably a really stupid question but I thought I ask...

I would like to get a high power exhaust fan for my bath. Most of them
use 6" duct to vent to the roof. My roof vent is 4" and I don't want to
change it.

Can I get a fan for 6" and then use a reducer to go from 6" to 4" duct
then to the vent?

Will this make it work "better" than a regular 4" exhaust fan?

I think this is a bad idea...

Get the highest CFM 4" unit you can find
