Use stainless steel for all your exhaust plumbing, and be prepared to change
it out occasionally. The rotary exhaust is HOT! Also, keep the exhaust length
as short as you can within the test cell and try to insulate and sheild the
exhaust from the intake as best as possible. You will need a lot of test cell
ventilation to keep reasonable intake air temperatures with that hot exhaust.
The heat has been the largest problem in my experience.
