Those baffels are resonators...specifically designed to eliminate air induction system noise. At least one of them is a helmholz resonator. That eliminates the howling sound of the air as it moves through the tube. The helmholz effect is like blowing across the opening of an empty pop bottle. Each resonator reduces/eliminates a specific frequency.
Removing the tube shouldn't put you into a lean condition (and subsequently throw a CEL) as long as you DON'T eliminate/bypass the mass airflow sensor in the system. The mass airflow sensor will compensate the fuel mixture and add fuel to the combustion process as the flow of air is increased due to a lower restriction induction system.
Besides...reducing restriction on the induction side will only have so much effect. The exhaust side still has a restriction so you won't really pump THAT much more air through the system.
