Dorman 674-090 Catalytic Converter with Integrated Exhaust Manifold - Right
Dorman 674-090 Exhaust Manifold Catalytic Converter
Dorman 674-090 is a catalytic converter with integrated exhaust manifold built for specific Nissan and INFINITI applications. It follows the original equipment layout for a direct replacement on the right side, with flanged inlet and outlet connections and a ceramic substrate.
Key Features
- Integrated exhaust manifold and catalytic converter in a one-piece design
- Precision-engineered to match OE fit and function on listed vehicles
- Stainless steel converter body with natural finish
- Ceramic substrate material
- Flanged inlet and outlet for secure mounting
- Includes inlet gasket, outlet gasket, studs, nuts, bolts, and washers as listed in the package contents
- Two sensor ports and two air tubes
- Not CARB certified and not New York certified
Detailed Description
This Dorman manifold converter is built for the right-side exhaust position on select 2016-2024 Nissan TITAN XD, 2016-2021 INFINITI QX80, 2017-2021 Nissan Armada, 2017-2021 Nissan NV2500, 2017-2021 Nissan NV3500, and 2017-2020 Nissan TITAN models. The one-piece construction combines the exhaust manifold and catalytic converter into a single assembly, helping restore the factory exhaust routing and emissions control layout on the listed applications. Part number 674-090 is a direct-fit replacement for vehicles that use the OE-style flanged manifold converter design.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Repair Uses
- Replacing a cracked or leaking exhaust manifold assembly
- Restoring catalytic converter function on the right side exhaust bank
- Addressing exhaust noise from flange or gasket sealing issues
- Correcting emissions-related faults tied to the manifold converter assembly
- Repairing damaged sensor-port or mounting-point hardware interfaces
Installation Notes and Tips
Verify right-side fitment before installation and confirm the vehicle is one of the listed Nissan or INFINITI applications. Use the included gaskets and supplied mounting hardware where specified in the package contents, and inspect the mating surfaces, studs, and sensor ports before assembly. Because this unit is not CARB compliant, confirm local emissions requirements before purchase. Part number 674-090 should be matched to the vehicle’s OE configuration for proper fit.
Quality Assurance
Dorman engineers this manifold converter to match original equipment dimensions and connection points for the listed applications. The stainless steel body, ceramic substrate, and OE-style flange layout support a factory-style replacement on compatible Nissan TITAN XD, TITAN, Armada, NV2500, NV3500, and INFINITI QX80 models. Part number 674-090 is built for direct replacement use on the specified right-side applications.
