What is the minimum federal emissions warranty requirement for an aftermarket replacement catalytic converter?

The minimum federal emissions warranty requirement for an aftermarket replacement catalytic converter is two years or 24,000 miles. This warranty is intended to cover defects in materials and workmanship, ensuring that the converter meets emissions standards over this specified period. The purpose of this regulation is to hold manufacturers accountable for the performance of their parts, especially since catalytic converters have a crucial role in reducing harmful emissions from vehicles. This warranty provides consumers with protection and peace of mind, ensuring that their replacement parts will function effectively and comply with federal emissions regulations for at least two years or 24,000 miles, which is a reasonable timeframe considering typical vehicle usage and the critical role of the catalytic converter in the vehicle's exhaust system. Other warranty periods, whether shorter or longer, do not meet the minimum federal requirement set for aftermarket catalytic converters.
