Dorman 673-933 Catalytic Converter with Integrated Exhaust Manifold
Dorman 673-933 Catalytic Converter Manifold
Dorman 673-933 is a catalytic converter with integrated exhaust manifold built for specific Nissan Altima applications from 2007-2012. It is engineered as a direct replacement for the original manifold converter, with CARB compliance for regulated emissions requirements.
- Integrated exhaust manifold and catalytic converter in a one-piece design
- Fits 2007-2012 Nissan Altima, N/A
- CARB compliant and California Air Resources Board certified
- Ceramic substrate with stainless steel converter body
- Flanged inlet and outlet for OE-style connection points
- Includes inlet gasket, outlet gasket, and mounting hardware listed in package contents
- Natural finish and natural color
OE-Style Replacement Construction
This Dorman catalytic converter manifold is precision-engineered to match original equipment dimensions and mounting points on the listed Nissan Altima years. The one-piece manifold converter design combines the exhaust manifold and catalytic converter into a single assembly, helping restore proper exhaust routing and emissions control on 2007-2012 Nissan Altima models. Part number 673-933 also cross-references 140E2JA93E for the same application.
Common Problems It Can Address
- Failed emissions testing caused by a worn or inefficient converter
- Exhaust leaks at the manifold-to-head or outlet connection
- Cracked or deteriorated original manifold converter housing
- Check engine light concerns related to catalyst efficiency or exhaust flow
- Noise from a damaged exhaust manifold assembly
Installation Notes
Verify the vehicle year and emissions configuration before installation. This part uses flanged inlet and outlet connections, includes one sensor port, and is supplied with inlet and outlet gaskets for OE-style fitment. Confirm all mounting points and port shapes match the original assembly on your Nissan Altima before beginning service. Part number 673-933 is intended for direct replacement use on the listed applications.
Quality Assurance
Dorman manufactures this manifold converter to match original equipment specifications for the listed vehicle applications. It is CARB compliant, California Air Resources Board certified, and New York certified for regulated-use applications.
