- Functionality of emission control devices, such as catalytic converters
Legal Standards for Exhaust Systems
Arizona law mandates that exhaust systems must be free of leaks, rust, or damage that could increase emissions. The catalytic converter must be present and functioning correctly, as it plays a crucial role in reducing harmful pollutants.
Common Reasons for Inspection Failures
