Your car’s catalytic converter can be worth a lot as scrap, which is why thieves keep stealing them. If you plan to scrap your own converter, it helps to know what it’s worth. If you’re not sure how to find the catalytic converter scrap value by serial number, we can show you.
In this guide, we show you how to find the value of your catalytic converter. We also talk about the catalytic converters with the highest value. There’s also a section that shows you what affects the value of a salvaged catalytic converter.
How to Look Up Catalytic Converter Scrap Value by Serial Number?
The best way to find your catalytic converter’s scrap value by serial number is to use a phone app or an online website. ConverterDatabase and Eco Cat are two of the most popular tools for this.
Here’s how to look up your catalytic converter’s scrap value using the serial number:
#1. Find the Serial Number
Before you can check your converter’s value, you need the serial number. Keep in mind, not all converters have one. The EPA says all newer cars must have a catalytic converter, but makers don’t have to stamp a serial number on it.
If your converter does have a serial number, it can be tricky to spot. We break down exactly where to look in the section below. You’re searching for an etched code made up of letters and/or numbers. It can be any length.
2. Use Online Platform/App
Once you have the serial number, type it into an online database to see its estimated value. If you want to search online, try ConverterDatabase. This site shows the current value of rhodium, palladium, and platinum.
You can also use a phone app. Many people pick Eco Cat, but you have lots of options. You can pay for a monthly subscription, or you can use the free plan that gives you one search per day.
3. Look Up Value with a Picture
If you cannot get the serial number or you just do not want to deal with it, you can take a picture and use an app. Eco Cat lets you do this.
Download the app from the Apple App Store or Google Play. After you upload the photo, the app sends you a quick quote for its worth.
Location of Catalytic Converter Serial Number
Most catalytic converter serial numbers are located in the center of the outer shell or on the connecting flanges where the unit bolts to the exhaust pipe.
Finding these physical ID markers means you need to understand how manufacturers choose where to etch them. Automotive engineers usually place these stamps on strong areas built to handle extreme heat cycles without warping or wearing down the text.
You’ll typically find these markings in these spots:
- Center body shell
- Inlet pipe flange
- Heat shield underside
- Side-wall stampings
Because the main canister gives you the largest flat surface, it’s often the first choice for high-visibility stamping. Workers frequently press these marks into the stainless-steel during assembly so they stay permanent even after years of tough use.
If you don’t see the number right away on the shell, check the flanges next. These thicker metal joints give you a stable base for heavy pneumatic stamping, so they resist the deep rust that often eats away at the thinner shell material.
Note: Start your search at the flattest part of the canister for the fastest results.
Keep in mind that the location changes a lot depending on whether the part is original equipment or a replacement.
OEM vs. Aftermarket Serial Number Placement
OEM converters usually show deeply etched manufacturer logos and 10–12-digit strings, while aftermarket units often use smaller, laser-etched tags or welded plates.
You need to tell these two types of parts apart for PartDifferentiation. Original Equipment Manufacturer (OEM) units meet much stricter durability standards, and this shows in how the identification marks are built.
| Feature | OEM | Aftermarket |
| Logo | Present | Rare |
| Code Length | Long/Complex | Short/Simple |
| Placement | Integrated | Surface Tag |
Identifying OEM Manufacturer Marks
OEM units usually have the serial number built right into the metal housing. You will often see a manufacturer logo like Ford, GM, or Toyota stamped next to a long mix of letters and numbers. These marks are made to last as long as the vehicle does.
Identifying Aftermarket Approval Codes
Aftermarket units often use a welded ID plate or a laser etch on the surface. These units must show an Executive Order (EO) number or a CARB code to prove they meet legal rules, but the mark may not be as tough as the factory stamps on original parts.
Note: OEM marks are built to last the life of the vehicle and are less likely to fall off over time. Rust and other wear can still make these marks hard to see.
How to Reveal a Hidden or Rusted Serial Number
To reveal a rusted serial number, spray on a specialized degreaser and gently scrub the surface with a fine-wire brush. Do not grind away the shallow etchings.
Road salt and high-heat oxidation can quickly hide even the deepest stamps. Using proper Restoration Techniques is vital so you do not damage the metal shell. If you handle it too aggressively, you could cause exhaust leaks or total part failure.
Recommended Cleaning Tools
To safely clean the metal surface, gather these supplies:
- Steel wool (0000 grade)
- Brake cleaner
- High-lumen LED flashlight
- Degreasing Agen
Avoid heavy-duty power grinders or coarse sandpaper. The heat and friction from power tools can burn off the thin layers of metal that hold the definition of the serial number.
The ‘Pencil Rub’ Transfer Method
If the number is barely visible, try a pencil rub. Place a thin piece of paper over the stamp and rub a graphite pencil over it. This will reveal the recessed edges of the numbers. It can often pick up details that a camera or your eye might miss in low-light conditions under the chassis.
Note: Gentle mechanical cleaning works better than chemical stripping on thin-walled exhaust components.
Once the number is visible, understanding its purpose is critical for maintenance and value.
Common Serial Number Formats by Manufacturer
Different manufacturers use different coding systems, and knowing what to look for can help you spot your converter faster.
- Ford converters often carry codes like “XL34-5E214-JD” or the torpedo style “1C2C 5E212 AA”. The Ford torpedo ranks among the most valuable domestic converters, with prices running from $110 to $1,141 based on how many biscuits sit inside. A 4-biscuit torpedo can top $1,100, while a 2-biscuit unit might only fetch $110 to $400.
- Honda stamps codes right on the converter shell. Honda Civic converters usually sell for $75 to $350, with most OEM units going for $150 to $250. Honda Accord converters land in the $80 to $300 range, and 1996 to 2007 model years pay the best.
- Subaru vehicles often come with two converters, and the small “bean cat” often pays more than the front one. Subaru Outback and Forester sets can reach $300 to $600 total. Keep those heat shields with the stamped codes.
- BMW converters span a wide range from $50 to $800 or more depending on the model. OEM BMW units pay several times what aftermarket ones do, so accurate identification matters.
How to Get an Accurate Quote Using the Serial Number
With your serial number in hand, you have several good ways to find out what your converter is worth.
- Online price databases and apps have become the go-to resource for many sellers. Platforms like Eco Cat, AutoCatalyst Market, and RRCats keep large, up-to-date catalogs of converter codes tied to current precious metal prices. You just type your serial number into their search bar, and the site shows you a price based on the exact platinum, palladium, and rhodium content for that converter model.
- These tools work by matching your code to lab test data from thousands of converters. An assay is a lab test that measures the exact amount of platinum, palladium, and rhodium in a converter. Trusted buyers keep databases of these assay results, so when you give them a serial number, they can look up the typical metal content for that exact converter type.
- Get multiple quotes before you decide. Prices can differ a lot between buyers because of their refining costs, current inventory needs, and profit margins. Send your serial number and photos to at least two or three different online buyers so you can compare their offers.
- Know the pricing tiers you might see. Standard light-duty gasoline converters usually sell for $50 to $250 at scrap yards. Hybrid vehicle converters, which hold more precious metals because their engines turn on and off more often, can bring up to $800 or more. High-value units from certain Ford, Honda, or BMW models can top $1,000 in some cases.
What Affects Your Converter’s Scrap Value?
Several factors beyond the serial number influence what you will actually be paid.
- Precious metal market prices fluctuate daily based on global supply and demand. Rhodium, for instance, peaked at nearly $30,000 per ounce in 2021 before crashing more than 80 percent to under $5,000 by late 2024. As of mid-2026, rhodium trades around $8,250 per ounce, palladium around $1,224 to $1,269 per ounce, and platinum near $2,346 per ounce. These spot prices directly impact what buyers will pay for your converter.
- Converter condition matters significantly. An intact converter with all its internal substrate (the honeycomb structure that holds the precious metals) will command a higher price than one that has been damaged, cut open, or had material removed. Buyers can often tell from your photos whether the substrate is ceramic or metallic, intact or broken, present or missing.
- OEM versus aftermarket is another critical distinction. Original equipment manufacturer (OEM) converters, which came installed on vehicles from the factory, contain far more precious metals than aftermarket replacement converters. An OEM Honda Civic converter might be worth $150 to $250, while an aftermarket unit from the same vehicle could be worth a fraction of that. The serial number helps buyers identify which type you have.
- Vehicle type and engine size play roles too. Larger engines and certain vehicle categories require converters with higher PGM loadings to meet emissions standards. This is why hybrid converters and those from trucks or luxury vehicles often bring premium prices.

To get a more accurate quote, you need information about your specific catalytic converter. You can try multiple platforms to see if one company offers more than another. If you don’t want to transport it or deal with the hassle, you can also post it online for scrap metal. Someone will likely pick it up and give you a portion of the money.
Preparing Your Catalytic Converter for Scrap
1. Cut Off Exhaust Pipes
On both ends of the catalytic converter, you’ll find the exhaust pipes. Cut these off as close to the metal shell as you can.
A Sawzall should handle the material just fine. If you leave the pipes on, the scrap yard will cut them for you and might charge you for the extra work.
2. Leave the Honeycomb In
When you look inside the catalytic converter, you’ll see a honeycomb-like structure. This mesh filters the exhaust fumes. It also holds the precious metals that make the catalytic reaction happen.
If you pull the honeycomb out, you’re basically throwing away the most valuable part. Keep it intact to get the best price. Many beginners accidentally remove it because they think it’s junk, but it’s actually what you want to keep.
What makes a catalytic converter valuable?
A catalytic converter is worth money because it holds a small amount of precious metals inside: platinum, palladium, and rhodium. These platinum-group metals coat a ceramic honeycomb and do the real work of cleaning your exhaust.
A typical converter holds only a few grams, but at today’s market prices, that adds up to real cash. That’s exactly why converter theft became so common.
How much is a catalytic converter worth? It comes down to three things: the type of vehicle (hybrids and large or European engines carry the richest loading), whether it is a factory or aftermarket unit (aftermarket cats have almost no precious metal), and the current price of rhodium and palladium, which move daily. That’s why the same-looking converter can be worth $80 on one car and $600 on another.
To get the most for a used converter, keep it whole and uncut, find the serial or part number stamped on the shell, and get quotes from more than one buyer against that number. Cutting it open or emptying the honeycomb almost always lowers what a buyer will pay.
Red Flags and Scams to Avoid
The catalytic converter scrap market has attracted bad actors, so protect yourself with these precautions.
- Never accept payment before shipping or delivering your converter to a verified buyer. Reputable companies will provide quotes based on your serial number and photos, then confirm the final price after receiving and inspecting the unit.
- Be wary of prices that seem too good to be true. If someone offers you $2,000 for a converter that online databases value at $200, they may be running a scam or planning to pay you in worthless currency.
- Verify the buyer’s credentials before sending anything. Legitimate recyclers maintain proper licensing, follow environmental regulations, and comply with laws like the PART Act designed to reduce converter theft.
- Document everything with photos and written communication. Keep records of your serial number, the quotes you received, and any agreements about pricing and payment terms.
- Understand legal requirements in your state. Many states now require detailed documentation when selling catalytic converters, including proof of ownership and identification. Selling without proper paperwork could get you into legal trouble, especially if the converter turns out to be stolen.
Step-by-Step Process to Maximize Your Return
Follow this workflow to ensure you get the best possible price for your catalytic converter:
- Remove the converter carefully if you are taking it off a vehicle yourself. Keep all heat shields and attached components, as they may contain the serial number.
- Clean and photograph the unit from all angles before doing anything else. Capture the full converter from both sides, close-ups of every serial number and part code, both inlet and outlet openings, flanges, sensor ports, and heat shields.
- Locate and transcribe the serial number using the guidance above. Clean rust with steel wool if needed, but do not damage the stampings.
- Identify the converter type as gasoline, hybrid, or diesel application. Note whether it is a pre-converter, main converter, DOC (diesel oxidation catalyst), DPF (diesel particulate filter), or SCR (selective catalytic reduction) component.
- Check online price databases using your serial number. Enter the code into multiple platforms to get a range of values.
- Request quotes from at least two or three buyers by submitting your photos and serial number. Compare their offers and ask about their payment terms, shipping policies, and any fees.
- Verify the buyer’s reputation through reviews, industry associations, or referrals. Ensure they are licensed and compliant with applicable laws.
- Ship or deliver the converter according to the buyer’s instructions. Use tracked shipping if mailing, and keep proof of delivery.
- Receive payment once the buyer confirms the converter matches your description. Most reputable companies pay within a few business days of receipt.
