Wanderer-
From one electrician to another...
I can't see any reason you couldn't bend exhaust pipe on a Conduit bender. 2" Rigid is what, 2.5" OD?
A Greenlee 555 probably won't bend it as tight as a hydraulic exhaust bender, but do-able.
You won't be able to expand or shrink the tubing like the exhaust shops can.
If you plan out your run, and keep your no-dog handy, you probably won't even need to shrink of expand anything.
