- Catalytic converter with integrated exhaust manifold for a manifold-converter design
- Fits 2011-2013 INFINITI QX56, left
- Fits 2014-2015 INFINITI QX80, left
- Stainless steel converter body with natural finish
- Round inlet with flanged outlet
- One sensor port for the specified application

Detailed Description
This Dorman catalytic converter manifold is precision-engineered to match the original equipment layout on the listed Infiniti vehicles. The stainless steel converter body, 4-inch converter body length, and 18-inch overall length support OE-style replacement needs for the left-side exhaust manifold assembly on the 2011-2013 INFINITI QX56 and 2014-2015 INFINITI QX80. Part number 674-299 is also cross-referenced to 57245 and 140021LA0C for the same application.
For buyers searching for a left catalytic converter for Infiniti QX56 or a left exhaust manifold converter for Infiniti QX80, this unit provides the correct integrated design with one inlet, one outlet, and an 8-hole inlet and outlet mounting pattern. Dorman 674-299 is a practical replacement when the original manifold converter is damaged, restricted, or no longer sealing properly.
What It Helps Fix
- Exhaust leaks at the manifold-to-cylinder head or outlet connection
- Restricted exhaust flow caused by a failing converter substrate
- Check engine light concerns related to converter efficiency or sensor-port issues
- Noisy exhaust operation from a cracked or warped manifold converter housing
- Failed emissions-related inspection results on the listed non-CARB applications
Installation Notes and Tips
Verify left-side placement, sensor-port location, and flange alignment before installation. Replace worn gaskets and inspect the mating surfaces for warpage, carbon buildup, or thread damage so the new manifold converter seals correctly. Confirm vehicle year and model match the listed fitment for the Infiniti QX56 or Infiniti QX80 before ordering.
Quality Assurance
Dorman manufactures this replacement as an OE-style manifold converter for the specified vehicles, with materials and dimensions selected to match the original exhaust layout. This part is not CARB certified.
