Emission control warranty
Asphalt roads are covered with the dark bituminous asphalt and stone / aggregate.
Concrete roads are made of material like portland cement and mineral aggregate, stone / gravel.
Here it is common for the water, sewer, and natural gas pipes to be under or next to the roadway. Commonly to be made of clay pipe, concrete pipe, steel. Many are old and needed replaced anyway.
The carbonic acid that drips out of a cold exhaust pipe will rapidly wear away the stone aggregate in the roadway.
If it gets in the soil it will wear through the pipes under the roadway.
Carbonic acid is what causes some underground caves to form, or enlarge.
Carbonic acid eats rock, stone, aggregate.
The warranty does not cover the exhaust system after the converter.
Not the muffler, not the pipe to the muffler, not the tail pipe.
Made of stainless steel now, to get some reasonable mileage / time of use from those parts.
E mission control, I think we have a problem.
Don't try this in a traffic jam kids.
The after engine catalytic converter is trying to cleanup a mess, after it has already been made. http://en.wikipedia.org/wiki/Timeline_of_alcohol_fuel
