Historical Prices for Half Cat



Half Cats aren’t a specific type of catalytic converter — they’re a way of describing converters that are missing part of the internal material that gives them value. This can happen when the ceramic or foil honeycomb inside becomes loose, breaks apart, or completely disintegrates due to heat, age, or damage.

Because half cats have lost some or all of their core material, their value is significantly lower than that of a full, intact converter. Pricing varies widely depending on how much usable material is left inside. The best way to determine what your Half Cat is worth is to send us detailed photos of the outside and, if safe, a clear shot of the inside material.

Once we receive your pictures, our team at RRCats will assess what’s left and provide a quote based on what can still be refined and recovered.

What Is a Half Cat?

A Half Cat is a catalytic converter that’s been partially or completely emptied of its internal core. This might happen naturally over time or through mechanical failure. While they still hold some value if partial material remains, they will not be worth as much as a full, complete converter.

We recommend not shaking out the material or attempting to clean out the converter. Keeping it in its current condition gives you the best chance at recovering value and lets our team accurately grade it for scrap pricing.

To find out what your Half-Cat is worth, send us a few photos, and we’ll provide a fast, honest quote.
