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..
Your engine and exhaust sytem are complicated pieces of machinery, and they also have a complicated relationship with the chemicals they spit into the atmosphere. One key way to minimize the pollution that's kicked out of your exhaust pipes is by using a catalytic converter, or cat converter.ith a Bassani Catalytic Converter or a Magnaflow Cat Converter you can open up some of the restrictions of your stock converter and get a crucial extra bit of performance. When upgrading or replacing your catalytic converter, it's important to know that not all catalytics are 50-state street legal.
