Dorman 673-820 Catalytic Converter with Integrated Exhaust Manifold - Rear
Dorman 673-820 Catalytic Converter Manifold
Dorman 673-820 is a catalytic converter with integrated exhaust manifold for specific Toyota Sienna applications. It is built as a direct-fit, standard replacement for the rear position on 2004-2006 Toyota Sienna models with CARB-compliant requirements.
For buyers searching for a 2004 Toyota Sienna rear catalytic converter manifold, 2005 Toyota Sienna exhaust manifold converter, or 2006 Toyota Sienna CARB-compliant replacement, this part is engineered to match the original equipment layout and connection points.
Key Features
- Direct-fit catalytic converter with integrated exhaust manifold
- Specific fit for 2004-2006 Toyota Sienna, rear
- CARB certified for listed applications
- Stainless steel construction with ceramic substrate
- One-piece, uncoated design
- Flanged inlet and outlet for OE-style mounting
- Heat shield attached for thermal protection
- Includes inlet gasket
Detailed Description
This Dorman manifold converter is precision-engineered as a standard replacement for the original exhaust manifold and catalytic converter assembly on the rear of the Toyota Sienna. The stainless steel body and ceramic substrate are selected for durability and emissions-system function, while the flanged inlet and outlet support a factory-style connection. The metallic gray, uncoated finish reflects the OE replacement format rather than a decorative finish.
Part number 673-820 is listed for 2004, 2005, and 2006 Toyota Sienna rear applications and is CARB certified for the specified fitment. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Failed catalytic converter efficiency codes on the rear exhaust system
- Cracked or leaking exhaust manifold converter assembly
- Exhaust odor or emissions-test failure tied to the rear converter
- Noise from a damaged manifold-to-exhaust connection
- Fitment issues from a worn OE-style manifold converter
Installation Notes and Tips
Verify the rear position and CARB-compliant requirement before ordering. Confirm flange alignment, inlet and outlet diameters, and gasket surfaces against the original assembly on the Toyota Sienna. Because this is a specific-fit exhaust component, proper sealing at the flanges is critical to prevent exhaust leaks and check-engine concerns.
Quality Assurance
Dorman manufactures this part as a precision-engineered OE-style replacement for the listed vehicle applications. Part number 673-820 is built to match original equipment fit and configuration for 2004-2006 Toyota Sienna rear installations.
