Additionally, you can check your vehicle’s documentation, such as the owner’s manual or service records, as the serial number might be recorded there. If you’re unsure whether the serial number is relevant, you can confirm its importance by consulting with scrap yards or online resources specializing in catalytic converter valuation.

Serial number location examples

The location of the serial number on a catalytic converter can vary depending on the manufacturer and model. Here are some common examples.


Stamped on the Casing: Look for the serial number stamped directly onto the metal casing of the catalytic converter. It might be located on the side or top surface.

Near Inlet or Outlet Pipes: Check near the inlet or outlet pipes of the catalytic converter. The serial number could be engraved or stamped in this area.

Underneath the Converter: Sometimes, the serial number is located on the underside of the catalytic converter. You may need to inspect it from underneath the vehicle.

On Manufacturer Tags: In some cases, the serial number might be on a manufacturer’s tag attached to the converter. This tag could be affixed to various parts of the casing.

Vehicle Documentation: If you can’t find the serial number on the converter itself, check your vehicle’s documentation. The serial number might be recorded in the owner’s manual, service records, or emissions-related documents.

Always consult your vehicle’s specific documentation or manufacturer guidelines for the most accurate information regarding the location of the catalytic converter serial number.

Catalyst device and value

The catalyst device, also called a catalytic converter, is part of a car’s exhaust system. Its job is to make harmful gases from the engine less dangerous before they leave the car. Inside, there are valuable metals like platinum.

These metals make the catalytic converter worth money. People who recycle metal will buy old catalytic converters because they can get the valuable metals out of them and reuse them. So, even though it’s part of a car, a catalytic converter has its own value too.

Catalytic converter device types and price valuation

Catalytic converters come in different types, mainly based on the materials used in their construction and the specific emissions control technologies they employ. The three primary types are.


  • Three-Way Catalytic Converters (TWC): These are the most common type and are designed to reduce three main pollutants: nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC). They contain precious metals like platinum, palladium, and rhodium.
  • Diesel Oxidation Catalysts (DOC): Specifically designed for diesel engines, DOCs primarily reduce emissions of carbon monoxide and hydrocarbons by oxidizing them into less harmful compounds. They usually contain platinum and palladium.
  • Selective Catalytic Reduction (SCR) Catalysts: Typically found in diesel vehicles, SCR catalysts use a chemical additive (urea) to convert nitrogen oxides into trogon and water vapor, reducing emissions. They do not contain precious metals like TWCs and DOCs.

The price valuation of catalytic converters depends on various factors, including.

  • Precious Metal Content: The value of platinum, palladium, and rhodium in the converter.
  • Converter Type: Different types contain varying amounts of precious metals.
  • Market Demand: Fluctuations in demand and prices for precious metals affect converter values.
  • Converter Condition: The condition of the converter, whether it’s new, used, or damaged, can impact its value.

Overall, prices for catalytic converters are determined by scrap yards and recyclers based on these factors and can vary widely

How to get the exact catalyst price?

Getting the exact price for a catalytic converter can be challenging due to various factors influencing its value, such as market fluctuations, precious metal content, and converter type. However, you can get an estimate of the catalyst price by following these steps.
