Dorman 673-317 Catalytic Converter with Integrated Exhaust Manifold - Left
Dorman 673-317 Catalytic Converter Manifold
Dorman 673-317 is a catalytic converter with integrated exhaust manifold built for direct replacement on select Lexus applications. It is engineered to match original equipment dimensions and mounting points for a straightforward repair on the left side of the exhaust system.
Key Features
- Integrated exhaust manifold and catalytic converter in one one-piece assembly
- CARB certified and CARB compliant with Executive Order D-798-9
- New York certified for regulated emissions applications
- Ceramic substrate with stainless steel converter body
- Flanged inlet and outlet for OE-style connection points
- Includes inlet gasket, outlet gasket, outlet mounting hardware, and mounting hardware listed in package contents
- Sensor port included for emissions system integration
Detailed Description
This manifold converter is designed for 2006-2011 Lexus IS350, left, and 2006-2009 Lexus IS250, left. The OE-style layout helps maintain the original exhaust routing while replacing the manifold and catalytic converter as a single assembly. Dorman 673-317 is built with a natural finish, stainless steel converter body, and ceramic substrate to support emissions system function in the specified vehicle applications.
This part cross-references Monroe Shocks & Struts (e.g., 1715031120) for the same application.
What It Helps Address
- Failed catalytic converter efficiency codes
- Exhaust leaks at the manifold-to-pipe connection
- Cracked or damaged integrated manifold assemblies
- Emissions test failures on regulated Lexus IS models
- Rattling or deteriorated converter internals
Installation Notes and Tips
Verify left-side fitment before ordering. Confirm flange alignment, sensor port location, and gasket surfaces against the original part. Because this is a CARB-certified emissions component, installation should match the exact vehicle year, make, model, and position listed for proper compliance.
Quality Assurance
Dorman manufactures this manifold converter as an OE-style replacement for specific Lexus applications, with CARB certification and New York certification documented for the listed fitments. Part number 673-317 is built to align with original equipment specifications for the vehicles shown above.
