How to photograph a catalytic converter for a quote

Catalytic converters are quoted per unit, and the photo is what tells us which unit it is. With these photos we can answer faster and with fewer back-and-forths.

The photos we need

• Whole unit: the entire converter with both ends (inlet and outlet) visible, on a plain background if possible.
• Code: a close-up of the number stamped on the shell or on the welded plate. That number identifies the exact model.
• Logo or brand: if the car maker logo (Toyota, Honda, Ford, BMW, etc.) or the converter brand is visible, a close-up.
• Heat shield or labels: if present, they help too.

Tips so the code is readable

• Daylight or a lamp from the side; avoid direct flash, which washes out the stamp.
• Wipe off dust or rust with a cloth or soft brush. Do not sand or grind the code.
• Shoot straight on, about 8–12 inches away, focused on the number; if it is not readable, try another light angle.
• If the code is on two lines or wraps around the shell, take several photos.

If you have many units

Sort them by type (OEM with code, hybrid, diesel/DPF, aftermarket) and tell us how many of each. For a lot of identical units, send a few examples and the quantity. We buy wholesale, by the full container or full load, and converters can share a container with e-scrap.

Identify your converter from a photo

Try our catalytic converter identifier: upload a photo and the AI tries to read the code and brand and match them against our code database. It is a beta tool, it can be wrong and it shows no prices; Yoan confirms each unit from your photos.

FAQ

Where is the code on a catalytic converter?

Usually stamped on the metal shell or on a welded plate, often on the underside or near one end.

Do you give a price from the photo?

We quote from your photos and quantity. We do not publish converter prices on the site because they depend on the exact unit.
