Key Features

• Fitment: Built to be compatible with Toyota Corolla and Chevrolet/Prizm 1998-2002 1.8L engines so buyers can select a direct-fit replacement for those models.
• OEM Specification: Matches common OEM part numbers (15844, 642939, 40243) so it aligns with factory intent for emissions and mounting points when fitment is correct.
• Durable construction: Stainless steel body with aluminized pipes resists rust and helps ensure a longer service life under normal driving conditions.
• Catalytic core design: Double-layer high temperature resistant ceramic carrier increases flow area which can assist engine breathing and fuel economy after installation.
• Includes installation hardware: The kit ships with necessary gaskets and hardware to simplify replacement and reduce the need to hunt for additional parts during installation.
• EPA compliance: Certified to EPA requirements for aftermarket converters outside restricted states, providing a compliant option where allowed.

Who It's For

This converter kit is aimed at owners of 1998-2002 Toyota Corolla and Chevrolet/Prizm with the 1.8L engine who need a replacement catalytic converter that follows OEM specifications and is EPA compliant in most states. It is a good match for independent mechanics and experienced DIYers who want a mostly plug-and-play swap and value corrosion-resistant materials.

It is not suitable for customers in states where EPA aftermarket converters are restricted, such as California and Colorado, or where local regulations prohibit this type of unit. Buyers who need a guaranteed factory-original part or state-specific certified converters should look for an exact dealer-sourced unit or a local emissions-certified alternative.
