Cars rust from moisture (rain, snow, etc.), especially collecting in crevices where it can't readily evaporate and where dirt also is trapped and holds the moisture. Additional corrosion occurs in areas that use salt on roads in the winter. The salt not only is corrosive to the metal but will also damage the car's finish.
One reason why car exhausts rust faster than the car body of the car is because they are often at a different temperature. The exhaust can be very hot and very cold so this creates a reaction rate which inturn makes the exhaust rust faster. hope that helps :)
