I seriously doubt any emissions place is going to be able to tell that you have removed your smog pump. I wouldn't worry about the visual at all, they generally just look at the catalytic converters. The smog pump is there to bring the converters up to temperature. Once the car has reached operating temperature, it serves no purpose. That is why most modern cars have electric smog pumps. Removing the smog pump should have no effect on your emissions test, so long as you give the car for 15 minutes prior to the sniffer.
