Footnote #48

Helpful hint to extend the life of your exhaust system:  Exhaust system corrosion will occur if moisture (condensation) is not cleared out of the exhaust system.  Make sure the vehicle is driven at least 20 to 30 minutes when ever the car is started to completely dry out all liquid/acid that is created by the combustion process in the engine.  Failure to do so will cause pre-mature rotting of the exhaust, from the inside out.
