Dorman 673-898 Catalytic Converter with Integrated Exhaust Manifold - Rear
Dorman 673-898 Catalytic Converter Manifold
Dorman 673-898 is a catalytic converter with integrated exhaust manifold for specific BMW applications. It is built as a direct-fit, standard replacement for the rear position on 2001-2003 BMW 525i and 530i models with CARB-compliant coverage.
Key Features
- Integrated exhaust manifold and catalytic converter design
- Specific fit for 2001-2003 BMW 525i and 530i, rear
- Stainless steel construction with an uncoated metallic gray finish
- Ceramic substrate material
- Flanged inlet and flanged outlet for OE-style connection points
- CARB certified for listed applications
- Includes inlet gasket
Product Details
This manifold converter is engineered to match original equipment dimensions and mounting points on the listed BMW 525i and 530i applications. The one-piece stainless steel body uses a ceramic substrate and flanged inlet/outlet design to support a direct replacement for the rear exhaust position. Dorman 673-898 is a practical choice when replacing a worn or failed catalytic converter on 2001-2003 BMW 525i and 530i models that require CARB-compliant coverage.
This part cross-references 452298 and 452431 for the same application.
Common Issues It Can Address
- Failed catalytic converter efficiency on the rear exhaust section
- Exhaust leaks at the manifold-to-pipe connection points
- Check engine light concerns related to catalyst performance
- Corrosion or cracking in the original manifold converter assembly
- Fitment problems caused by a damaged OE-style exhaust manifold converter
Installation Notes and Tips
Verify the vehicle year, model, and rear-position fitment before installation. Confirm flange alignment, gasket surfaces, and outlet diameter match the existing exhaust system. Because this unit is specific to the listed BMW applications, compare the original assembly to the replacement before final tightening. Use proper exhaust sealing practices and follow factory service procedures for sensor and flange handling.
Quality Assurance
Dorman manufactures this catalytic converter with integrated exhaust manifold as a standard replacement part for the specified BMW applications. The design follows OE-style fitment requirements and is CARB certified for the listed vehicles.
