- Inlet gasket included
- CARB certified for the listed applications
Detailed Description
Dorman 673-9651 is engineered to match the original equipment layout on select Toyota Highlander, Toyota Sienna, Toyota RAV4, and Lexus RX350 models. The integrated manifold design helps replace the factory exhaust manifold and catalytic converter assembly in one unit, while the stainless steel housing and ceramic substrate support a standard replacement repair for front-position applications. This part cross-references Monroe Shocks & Struts (e.g., 171500P250, 5582250) for the same application.
Common Repair Issues
- Failed catalytic converter efficiency codes
- Exhaust leaks at the manifold-to-pipe connection
- Cracked or damaged manifold converter housing
- Check engine light related to emissions performance
- Heat shield damage or missing factory shielding
Installation Notes and Tips
Verify the vehicle year, make, model, and front position before installation. The 2014-2016 Toyota Highlander application requires a relearn procedure after installation; refer to the service manual for vehicle-specific instructions. Confirm flange alignment, gasket seating, and outlet diameter match the original exhaust layout before final tightening.
Quality Assurance
This Dorman manifold converter is a standard replacement part built for the listed specific-fit applications and is CARB certified where noted in the fitment data. Part number 673-9651 is intended for direct replacement on the confirmed Toyota and Lexus front applications shown above.
