Routine exhaust care starts with basic vehicle health. Fuel quality, ignition condition, leaks, and sensor readings can all affect how the exhaust system performs over time.
Maintenance checklist
- Address misfires, rough running, and strong exhaust smells early.
- Listen for new exhaust rattles or leaks.
- Do not repeatedly clear codes without checking why they return.
- Use maintenance products only as directed and only for suitable vehicles.
