Dorman 673-897 Catalytic Converter with Integrated Exhaust Manifold - Front
Dorman 673-897 Catalytic Converter Manifold
Dorman 673-897 is a catalytic converter with integrated exhaust manifold for specific BMW applications. It is built as a direct-fit, standard replacement with a flanged inlet and outlet, stainless steel construction, and a ceramic substrate for front exhaust service on select 2001-2003 BMW 525i and 530i models.
Key Features
- Direct-fit catalytic converter with integrated exhaust manifold
- Fits 2001-2003 BMW 525i, front
- Fits 2001-2003 BMW 530i, front
- Stainless steel body with uncoated metallic gray finish
- Ceramic substrate material
- Flanged inlet and flanged outlet for OE-style mounting
- Heat shield attached
- CARB certified for listed applications
- Inlet gasket included
Detailed Description
This Dorman manifold converter is precision-engineered to match original equipment dimensions and mounting points on the listed BMW 5 Series applications. The one-piece design combines the catalytic converter and exhaust manifold into a single assembly, helping maintain proper exhaust routing and emissions control on the front position of the 2001-2003 BMW 525i and 530i. Dorman 673-897 is a practical OE-style replacement when the original manifold converter is damaged, restricted, or no longer sealing correctly.
This part cross-references BMW OE numbers 18407504956 and 18407507347 for the same application.
What It Helps Address
- Exhaust leaks at the manifold-to-cylinder head connection
- Restricted exhaust flow from a failing catalytic converter
- Check engine light concerns related to catalyst efficiency
- Broken or warped manifold converter housing
- Emissions compliance issues on CARB-listed vehicles
Installation Notes and Tips
Verify the vehicle’s year, model, and front-position exhaust configuration before ordering. This unit uses flanged inlet and outlet connections and is specific to the listed BMW applications, so compare the original part shape, mounting points, and outlet dimensions during replacement. Because the heat shield is attached and the inlet gasket is included, inspect the surrounding exhaust hardware, studs, and sealing surfaces before installation to ensure a proper seal.
Quality Assurance
Dorman manufactures this catalytic converter manifold as a standard replacement part for specific vehicle applications. The CARB-certified listing applies to the vehicles shown in the fitment data, and the stainless steel construction is selected for exhaust-system durability in front-mounted service.
