Identifying Porsche Catalytic Converters for Scrap

How to Identify and Sell Porsche Catalytic Converters with RRCats

Porsche Logo

Porsche catalytic converters are most often classified as foil cats, meaning their value is typically determined by the weight and material composition of the unit rather than just the serial number. These converters are commonly found in Porsche’s high-performance exhaust systems and tend to carry substantial scrap value when original.

How To Confirm A Porsche OEM Catalytic Converter

Send clear pictures of the entire converter, including stamped markings and logos, for an accurate quote. Many Porsche catalytic converters may not have the iconic logo stamped on them, but they may have a stamp similar to the photos below that confirms that they are OEM parts. This stamp is called a “DP” (Deutsche Prüfzeichen or German Test) mark.

Common Serial Number Prefix:

Most Porsche converters’ serial numbers are located near the Porsche logo or stamp on the unit’s body, and they typically begin with the number 9-.

Using the below photos as an example:

  • Porsche part numbers usually follow a three-three-three format (9XX-XXX-XXX), sometimes with an extra suffix:

    • 996 — This is a Porsche model code, referring to the Porsche 911 model

    • 113 022 — This typically refers to the component type and its placement or version.

    • 53 — A revision or variant code.

This exact numbering style is widely used across Porsche OEM parts, including catalytic converters.
