I know I have to avoid exhaust system so it will be partial not full underbody.
How much fuel efficiency does this gain?
If anyone has done this in S. California, maybe they can do mine.

Back when bellypan studies were being conducted in the more modern wind tunnels,the underside of the car was attributed with about 12% of overall aero drag.
With a nicely executed pan you could cut that 12%.
At 55-mph,this would translate into a 6% mpg improvement.
At 70-mph,around a 7.2% improvement.
