Detailed Description
This manifold converter is precision-engineered to match the original equipment layout on select 2010-2017 Lexus RX450h and 2011-2017 Toyota Highlander models. Dorman 674-751 is designed for the right side and follows the OE-style manifold converter configuration used on these vehicles, making it a practical replacement when the original exhaust manifold and catalytic converter assembly needs service. This part cross-references NGK 52018 and 1714031410 for the same application.
For buyers searching for a 2011-2017 Toyota Highlander right catalytic converter manifold or a 2010-2015 Lexus RX450h right exhaust manifold converter, this part number provides a direct-fit option built around the original vehicle layout. The Dorman 674-751 part number is also useful when comparing OE-style replacement options for these Toyota and Lexus applications.
What It Helps Address
- Cracked or leaking exhaust manifold assembly
- Restricted catalytic converter flow
- Exhaust noise from a damaged manifold converter
- Check engine light concerns related to exhaust aftertreatment faults
- Failed emissions inspection caused by a worn converter assembly
Installation Notes
Verify right-side fitment before ordering, since this assembly is specific to the listed Toyota Highlander and Lexus RX450h applications. Confirm the inlet and outlet flange pattern, sensor port location, and mounting points against the original part. The package includes an inlet gasket, outlet gasket, bolts, nuts, washers, and studs; inlet mounting hardware is not included. Professional installation is recommended because exhaust fasteners and sensor connections may require careful handling during removal and replacement.
Quality Assurance
Dorman manufactures this catalytic converter manifold as a direct replacement part for specific OE applications, with construction and dimensions matched to the original equipment layout. Dorman 674-751 is built for the listed vehicle fitments and is not CARB certified.
