Who needs this part and when to replace

Typical reasons for replacement
While a catalyst is built to last, it can fail over time. Common triggers include:
- Physical impact from road debris or ground contact
- Thermal damage due to misfires or incorrect fuel mixture over a long period
- Age-related breakdown of the internal substrate
- Leaks at flanges, flex sections, or welds
