Regularly inspect the exhaust system for any signs of damage or corrosion. This can help catch potential issues early on before they become costly and difficult to fix.

Make sure to have the exhaust system professionally cleaned and serviced at least once a year. This will help keep it in good condition and prevent buildup of harmful substances.
