Environmental psychology addresses environmental problems such as density and crowding, noise pollution, sub-standard living, and urban decay. 1  Noise increases environmental stress.
Hayapower is correct. The tube from the converter is for the smog pump (air injection) for the catalytic converter. The EGR tube comes off the passenger side exhaust manifold. Disconnecting the tube from the converter will not hurt if you remove the conveter and close off the tube end or leave it open.If you leave it open then at times you will hear a pumping sound from the tube caused by the smog pump when it reaches proper temperature.t's thermactor/secondary fresh air injected from the smog air pump for converter/catalyst secondary burn/conversion.. Disabling/restricting an EGR flow (drastically), can/will result in a DTC.. The tube is needed for a fresh air suppy to the converter..
Re: 4 reasons why you should remove the AIR (smog) pump. 1. smog ***** who will deny your registration, making it illegal to drive on public roads. 2. smog, since as a human, i like to breathe, and the AIR pump gets the cat up to working temp faster so it converts CO, HC and NoX into CO2, N2 and H2O faster.e: 4 reasons why you should remove the AIR (smog) pump. I removed my AIR system many years ago, many engines ago. There was no increase in HP that is noticable, Engine ran exactly the same, Never ran any fast without the loss of the 3 lbs that the system weighed.
