Figure out a different way to do it. What you wanting to do there is basically reducing down to a 4" tight 90* elbow & that's going to kill airflow. Something that might work is to make a duct out of plywood & then put turning vanes inside to tame the turbulence. They can be had from an HVAC duct supplier. You would want to make it oversize as well & then fabricate a reducer to fit the outlet.

Any chance you can post a picture?

What drzaius and RichardA said; find another way, you will hurt your airflow too much with your plan.  Many times people do not think about back-pressure in DC systems.  If your filter bag is blowing up like a balloon, get more filter media.  Exhausting outside is Nirvana, don't exit the freeway into a wall.
