How to Sell Your GM Catalytic Converter

GM Logo

Replacing a catalytic converter on your General Motors (GM) vehicle can be an expensive repair. Whether you drive a Chevrolet Silverado, GMC Sierra, Cadillac Escalade, Chevrolet Tahoe, GMC Yukon, or another GM vehicle, your original OEM catalytic converter may still have recycling value after it’s been replaced.

Many GM catalytic converters contain valuable precious metals such as platinum, palladium, and rhodium. Recovering value from your original converter can help offset part of your replacement costs.

In this guide, you’ll learn:

  • Can you sell your GM catalytic converter after replacement?
  • How to make sure you get your original converter back
  • What makes GM catalytic converters valuable
  • How to identify GM serial numbers
  • How to sell your converter through RRCats

Can You Sell Your GM Catalytic Converter After Replacement?

Nearly always, the answer is yes. If your GM catalytic converter has been replaced, there’s a good chance the original OEM converter still has recycling value.

Even if it no longer functions properly, the precious metals inside can often be recovered and refined.

The value of your converter depends on several factors, including:

  • Whether it’s an OEM GM converter
  • Vehicle make and model
  • Current platinum, palladium, and rhodium prices
  • Physical condition
  • Correct serial number identification

The easiest way to determine its value is by requesting a free quote from RRCats.

What Makes GM Catalytic Converters Valuable?

Every catalytic converter is different.

The recycling value depends on the amount of recoverable precious metals inside, along with the converter’s design and serial number.

Factors that influence value include:

  • Chevrolet, GMC, Cadillac, or Buick model
  • OEM versus aftermarket construction
  • Current precious metal markets
  • Physical condition
  • Correct serial number identification
  • Number of catalytic converters on the vehicle

Many GM trucks and SUVs have multiple catalytic converters, meaning you may have more than one OEM converter with recycling value after a repair.

Learn more about replacement costs in our GM Catalytic Converter Replacement Cost Guide.

How Much Is My GM Catalytic Converter Worth?

There isn’t a single value for every GM catalytic converter.

Two converters from similar Chevrolet Silverado or GMC Sierra trucks can have completely different recycling values depending on their serial numbers and internal construction.

Instead of estimating based on appearance alone, RRCats identifies each converter individually to provide the most accurate quote possible.

The fastest way to receive a quote is by sending:

  • The stamped serial number
  • Clear photos of the converter
  • Photos of any visible markings

Ask Your Mechanic for Your Original Catalytic Converter

Before authorizing your repair, ask your repair shop if your original catalytic converter will be returned to you.

Many repair facilities automatically recycle removed converters unless the customer specifically requests them back.

Helpful questions include:

  • Can I keep my original catalytic converter?
  • Will every catalytic converter removed from my vehicle be returned?
  • Do you automatically recycle old converters?
  • Is there any paperwork I should keep?

This is especially important on many Chevrolet and GMC trucks, which often have two or more catalytic converters.

Legal Considerations

Catalytic converter laws vary by state.

Depending on your location, you may need:

  • Proof of ownership
  • Government-issued identification
  • Vehicle documentation
  • Additional paperwork

RRCats follows all applicable state and federal regulations when purchasing catalytic converters.

Identifying GM Catalytic Converters & Serial Numbers

Tom shares tips on identifying the serial numbers from a GM catalytic converter. Knowing where to find the GM serial numbers will help our team give you an accurate and fair price quote.

Finding GM Catalytic Converter Serial Numbers

One advantage of GM catalytic converters is that they’re often among the easiest OEM converters to identify.

Approximately 90% of OEM GM converters have serial numbers stamped directly onto the converter housing or main heat shield.

Common serial number prefixes include:

  • 126
  • 127
  • 253
  • 255

Unlike some other manufacturers, GM catalytic converters typically don’t have secondary heat shields covering these numbers.

Pro Tip: If the serial number is dirty or difficult to read, gently cleaning the stamped area with steel wool can make the numbers much easier to see.

If you’re still unsure, simply send us clear photos and our team will help identify your converter. Use the guide below to help identify your converter.
