Abstract

An exhaust system is disclosed that has pipes and a housing, through which exhaust fumes of an internal combustion engine flow. The exhaust fumes generate a condensate, at least in part and/or in certain areas. To prevent the corrosion of sheet metal by the condensate, a sacrificial anode, which can be made of zinc and/or magnesium, is provided at least in one of the areas where the condensate collects.
