From the Paxton Website:

On the left is the curved-discharge volute; the unit on the right is our completed Novi 2000 with its new, straight-discharge volute. The volute measures 4 inches on the intake side and 3 inches at the discharge opening. If you want Paxton to perform the volute swap only (although we highly recommend having your blower serviced, too), the conversion from curved-to-straight discharge will set you back $238.95 for parts and labor.

Does this mean they could swap back for the same price?

Food for thought.
