It's recommended to have your exhaust system checked at least once a year or every 12,000 miles, whichever comes first.
Common indicators include increased engine noise, decreased fuel efficiency, a noticeable smell of exhaust fumes inside the vehicle, and visible rust or damage to exhaust components.
Driving with a compromised exhaust system can be dangerous due to potential exposure to harmful gases and can lead to further engine damage. It's best to have it inspected and repaired promptly.
