| Origin | 🇩🇪 Germany Manufactured here Leistritz, Germany. |
| Process | Fabricated / Welded |

| Notes | Leistritz sold its exhaust division to Faurecia in 1994 with ten-year naming rights, so anything sold as a new Leistritz Porsche system today is old stock, a later Faurecia-era part, or mislabelled. Worth knowing before paying an OEM premium. |
