Product Details

The Dorman Pre-Catalytic Converter (also called a pre-cat or front catalytic converter) is a federal EPA-compliant emissions control part. It is designed to replace the original pre-converter on your exhaust system. A pre-cat sits close to the engine. It heats up quickly and starts reducing harmful exhaust emissions soon after startup.

Key Features:

  • Federal EPA compliant for use in states that follow federal emissions standards
  • Catalyst substrate converts hydrocarbons, carbon monoxide and nitrogen oxides into less harmful gases
  • Built as an aftermarket replacement for the original pre-converter
  • Durable metal housing is made to withstand exhaust heat, vibration and road conditions
  • Helps restore emissions performance and clear catalyst-efficiency fault codes caused by a failed converter

Dorman has a long record of supplying aftermarket replacement parts. Each part in this line is built to replace the original component and help your vehicle meet emissions requirements. Select the specific part number for your application from the options on this page.
