Abstract
A process for manufacturing an exhaust system for an internal combustion engine includes the steps: a) providing at least one exhaust gas-carrying component (12, 18) for the exhaust system (10); b) applying a basic material layer (24, 26) to at least one area of a surface of at least one of the exhaust gas-carrying components (12, 16) in a high-temperature application process; and c) applying a catalytically active material layer (28, 30) to the basic material layer (24, 26) in a low-temperature application process.

A process for manufacturing an exhaust system for an internal combustion engine, the process comprising the steps of:
- providing at least one exhaust gas-carrying component for the exhaust system;
- applying a basic material layer to at least one area of a surface of the at least one exhaust gas-carrying component in a high-temperature application process;
- and
- applying a catalytically active material layer to the basic material layer in a low-temperature application process.
An exhaust system for an internal combustion engine, the exhaust system comprising at least one exhaust gas-carrying component comprising a metallic material and a catalyst coating comprising a basic material layer and a catalytically active material layer on the basic material layer.
