As long as the MAF housing and sensor is unchanged the diameter of whatever is feeding it makes no difference... As long as it is bigger than the MAF housing diameter the air will have to speed up as it passes through in order to maintain the same volume of flow. Since the volume is set by the throttle opening and the engine load then the amount of air flowing through the intake is constant at a steady engine state even though the velocity may be changing dramatically as it twists and turns and expands and contracts through the system. You can run the car with nothing at all connected to the housing on the filter side and as long as the sensor works and there is no vacuum leaks on the intake side it will work just fine. Not that I recommend running without an air filter.
