Detailed Description

This Dorman catalytic converter, part number 674-486, is made for 2010-2011 Chevrolet Equinox front left and 2010-2011 GMC Terrain front left applications. The converter uses a cylindrical body design with a 13-inch overall length, stainless steel construction, and a ceramic substrate to match the original exhaust layout on the specified vehicles. The flanged inlet and outlet connections support a direct-fit installation where the factory configuration calls for this style of mounting. This part cross-references Walker Exhaust (e.g., 16670, 52230) for the same application.

What It Helps Address

• Failed catalytic converter efficiency codes
• Exhaust restriction from a damaged internal substrate
• Emissions-related drivability concerns tied to converter wear
• Exhaust leaks at the inlet or outlet flange areas
• Replacement needs after corrosion or physical damage to the original converter

Installation Notes and Tips

Verify the vehicle’s year, make, model, and front left position before ordering. Confirm the inlet and outlet flange style, sensor port count, and exhaust dimensions against the original unit to ensure proper alignment. This converter includes inlet and outlet gaskets plus mounting hardware for the listed application, and the flanged design is intended for vehicles that match the OE exhaust configuration.
