Diesel catalytic converters are found on vehicles with diesel engines and are designed to reduce emissions like gasoline counterparts. However, many diesel converters tend to be lower in value due to the reduced amounts of precious metals like platinum, palladium, and rhodium inside. On average, Diesel Cats range in price from $15 to $477, depending on the type, condition, and content.

While many diesel cats are on the lower end of the pricing scale, there are exceptions—some models, especially those from heavy-duty or commercial vehicles, can be decently priced. Since there’s no easy way to tell just by looking, we always recommend sending clear photos of your converter (including any visible serial numbers) so our team can provide an accurate, up-to-date quote.

We evaluate each diesel converter based on internal structure, brand, and market conditions. Submit your photos to our team at RRCats, and we’ll let you know exactly what your diesel cat is worth.

What Is a Diesel Catalytic Converter?

Diesel Cats are converters designed specifically for diesel-powered vehicles. Unlike typical gasoline engine converters, diesel cats may not always contain high levels of precious metals, making them less valuable in many cases. However, certain OEM diesel units — especially those from trucks, vans, or industrial engines — may still hold scrap value.

To determine whether your diesel cat is valuable, the best step is to send us photos of the full converter and any serial numbers. We’ll quickly review it and provide a fair, accurate quote based on our current diesel grading scale.
