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..
Before you read any further, I must tell you that removing the catalytic converter is illegal. I strongly advise that you DO NOT remove it. You will be in violation of Feder â¦ al and most state laws. That being said, the biggest negative effect, as stated, is that is illegal.ome engines need some back pressure to run efficiently. Removing the catalytic converter and the muffler, and increasing the diameter of the pipes too much will decrease the velocity with which the exhaust gases move, which will actually cause more restrictions on the engine.
