Dorman 679-577 Catalytic Converter with Integrated Exhaust Manifold

Dorman 679-577 Catalytic Converter with Integrated Exhaust Manifold

OE-Style Exhaust Manifold Converter

Dorman 679-577 is a catalytic converter with integrated exhaust manifold built as a direct replacement for specific Nissan applications. It combines the manifold and converter in a one-piece, flanged design to match the original equipment layout on 2019-2021 Nissan Altima models.

Built from stainless steel with a ceramic substrate, this standard replacement part is engineered for the exhaust flow and mounting requirements of the original assembly. The integrated heat shield and included inlet gasket support a cleaner, OE-style service replacement for the Nissan Altima exhaust system.

Key Features

  • Direct-fit catalytic converter with integrated exhaust manifold
  • Specific fit for 2019-2021 Nissan Altima
  • Stainless steel construction with uncoated metallic gray finish
  • Ceramic substrate material for exhaust aftertreatment service
  • One-piece, flanged inlet and outlet design
  • Heat shield attached for added thermal management
  • Inlet gasket included
  • Standard replacement grade from Dorman

Detailed Description

Dorman 679-577 is a manifold converter designed to replace the original exhaust manifold and catalytic converter assembly on the Nissan Altima. The round body, flanged connections, and specific-fit dimensions are matched to the OE configuration for 2019, 2020, and 2021 models. This part cross-references OE numbers 208A26CU0A and 208A26CU0C for the same application.

For buyers searching for a 2019-2021 Nissan Altima catalytic converter with exhaust manifold, Dorman 679-577 provides a direct replacement solution that follows the factory-style layout. It is not CARB certified, so it should be selected only where that emissions configuration is appropriate.

Common Problems It Can Address

  • Cracked or leaking exhaust manifold assembly
  • Restricted exhaust flow from a failing converter
  • Exhaust leaks at the manifold-to-pipe connection
  • Check engine light related to catalyst efficiency or exhaust sealing issues
  • Noise from a damaged integrated manifold/converter unit

Installation Notes

Verify vehicle application before installation: Fits 2019-2021 Nissan Altima, N/A. Confirm flange alignment, inlet and outlet dimensions, and sensor or gasket requirements against the original assembly. Because this is a specific-fit exhaust component, proper sealing and torque procedure are important for leak-free operation.

Quality Assurance

Dorman designs this manifold converter to match original equipment fit and function on the listed Nissan Altima applications. The stainless steel body, ceramic substrate, and integrated heat shield reflect an OE-style replacement approach for exhaust service.
