What is the average lifespan of an Audi A4 exhaust system?

I've recently purchased a used Audi A4 and I'm curious about the maintenance required for the exhaust system. What is the typical longevity of this component and when should I start keeping an eye on it?

The average lifespan of an Audi A4 exhaust system is around 5-7 years, depending on driving habits and geographical location. However, regular maintenance and proper care can extend its lifespan.

As a general rule of thumb, it's best to have your exhaust system inspected every 50,000 miles or so. This can help identify any potential issues before they become major problems.
