Dorman 673-9891 Catalytic Converter with Integrated Exhaust Manifold - Front
Dorman 673-9891 Catalytic Converter Manifold
Dorman 673-9891 is a catalytic converter with integrated exhaust manifold for specific front-position applications. It is built as a standard replacement in stainless steel with a ceramic substrate, matching the original equipment layout for direct-fit service on select Chevrolet Colorado, GMC Canyon, Hummer H3, and Isuzu i-370 models.
Key Features
- Integrated exhaust manifold and catalytic converter design
- Specific fit for front exhaust applications
- Stainless steel construction with uncoated metallic gray finish
- Ceramic substrate material
- Flanged inlet and flanged outlet for OE-style connection points
- CARB certified for listed applications
- Inlet gasket included
Detailed Description
This manifold converter is engineered to match the original equipment configuration on the listed vehicles, helping maintain proper exhaust routing and emissions system function. Dorman 673-9891 uses a one-piece, round-body design with a flanged inlet and outlet, making it a direct replacement for front-mounted exhaust manifold converter applications on 2007-2012 Chevrolet Colorado, 2007-2012 GMC Canyon, 2007-2008 Hummer H3, and 2007-2008 Isuzu i-370. This part cross-references Monroe Shocks & Struts (e.g., 5481353, 5582353) for the same application.
What It Helps Address
- Failed catalytic converter efficiency codes
- Exhaust leaks at the manifold-to-pipe connection
- Cracked or deteriorated manifold converter assemblies
- Emissions test failures on CARB-regulated applications
- Noise caused by a damaged front exhaust manifold assembly
Installation Notes and Tips
Verify the vehicle year, make, model, and front-position exhaust configuration before installation. Confirm flange alignment, gasket condition, and outlet diameter match the existing exhaust system. Because this is a specific-fit replacement, compare the original assembly to Dorman 673-9891 before removal to ensure the correct application for your Chevrolet Colorado, GMC Canyon, Hummer H3, or Isuzu i-370.
Quality Assurance
Dorman manufactures this manifold converter as a standard replacement part for OE-style fit and function on the listed applications. CARB certification is noted for the covered vehicles, supporting emissions compliance where required.
