Why Are Old Catalytic Converters Valuable?
Old catalytic converters might seem like junk, but they’re actually treasure troves of precious metals like platinum, palladium, and rhodium. These rare and expensive metals are what make converters valuable, even when they no longer function. Depending on the amount and condition of these metals, you could be looking at hundreds of dollars for your old converter.
What is a Catalytic Converter?
A catalytic converter is a crucial part of your car’s exhaust system. It reduces harmful emissions by converting dangerous gases like carbon monoxide and nitrogen oxides into less toxic substances before they leave your vehicle.
These converters work by using precious metals such as platinum, palladium, and rhodium, which act as catalysts for the chemical reactions that clean your car’s exhaust.
Introduced in the 1970s and required on all U.S. vehicles by 1975, catalytic converters typically last 10 to 15 years. However, over time, the metals can degrade, and the converter will eventually need to be replaced.
If you’re wondering whether your old catalytic converter still has value, the short answer is: Yes, it does! The precious metals inside can still be recycled, even after the converter is no longer functional.
When Is It Time to Sell Your Old Catalytic Converter?
Knowing the right time to sell can ensure you get the most value:
- After Replacing Your Converter: If you’ve replaced your converter due to mileage, performance, or inspection failure, the old one can still hold significant value.
- When Prices Are High: Metal markets are always changing, so keep an eye on platinum and palladium trends.
How Do You Know You Should Replace Your Catalytic Converter?
- Failed Emissions Inspections
- A failed emissions test is one of the top reasons people need to replace their catalytic converter. Many states require these tests to ensure vehicles meet pollution standards. If your car fails, the old converter likely needs to be replaced—and that means it’s time to recycle it for cash.
- Mileage Milestones
- Catalytic converters typically wear out after 150,000 miles or more. By this point, the internal metals may have degraded, reducing the converter’s effectiveness. If you’ve reached this mileage threshold, consider replacing the converter and recycling the old one for value.
- Decreased Vehicle Performance
- If your car struggles with poor acceleration, reduced fuel efficiency, or unusual noises during driving, your catalytic converter could be failing. An illuminated “check engine” light is another common indicator.
- Unusual Smells or Smoke
- A failing catalytic converter can sometimes emit a rotten egg smell from the exhaust or produce dark smoke. These are signs that the converter isn’t effectively cleaning your car’s emissions anymore.
When any of these issues arise, replacing the catalytic converter is necessary—but don’t toss the old one. Instead, sell it to a trusted buyer like RRCats.com through the iScrap App for a hassle-free process.
How Do I Know My Old Catalytic Converter Is Valuable?
The value of your catalytic converter depends on:
- Metal Content: OEM converters often contain higher amounts of precious metals compared to aftermarket parts.
- Condition: The amount of recoverable metals determines the price you’ll receive.
- Market Prices: Platinum, palladium, and rhodium prices fluctuate, so timing matters.

Preparing Your Catalytic Converter for Sale
Now that you know how to sell your converter and who will buy it, the next step is preparing it for shipping. The first thing you’ll need to do is remove it from your car. The catalytic converter is usually under the vehicle, on the underside of the engine near the exhaust manifold.
You will likely need a Sawzall or similar tool to cut the converter off. Once it’s removed, take pictures of any identifying marks on the converter, including the serial number. These marks will help RRCats give you an accurate quote for your converter. If you can’t find the serial number, don’t worry—RRCats will still be able to give you a quote.
Note that aftermarket converters usually lack identifying marks and are usually worth less than the original pieces.
CHECK PRICES
You can use whatever you have on hand for packaging. A cardboard box or a garbage bag will work just fine. Ensure your converter is well-protected so it doesn’t get damaged in transit. Packing peanuts, bubble wrap, and old clothes are all great options for padding.
However, it is sturdy, so you don’t have to worry too much.
Once your package is in transit, you only have to sit back and wait for payment. RRCats will send you an email as soon as they receive your converter, and you’ll usually have your money within 24 hours if you choose PayPal.
