Product Details

Dorman 679-527 is a standard replacement catalytic converter with a cylinder body shape, flanged inlet and outlet, and one inlet and one outlet connection. The unit uses a ceramic substrate and stainless steel housing for the specified OE-style layout. It is not CARB certified, so it is listed for non-CARB-compliant applications only. This part cross-references Bosch 16581 for the same application.

Common Repair Uses

• Replacing a failed front catalytic converter on a Chevrolet Equinox
• Restoring exhaust flow on a GMC Terrain with converter restriction
• Addressing emissions-related trouble codes tied to converter efficiency
• Repairing exhaust leaks at the flanged inlet or outlet connections
• Replacing a damaged converter on a Chevrolet Captiva Sport front exhaust system

Installation Notes

Verify the vehicle year, make, model, and front-position exhaust layout before installation. Use the included inlet and outlet gaskets during assembly, and confirm the sensor port location matches the original exhaust configuration. Because mounting hardware is not included for every connection point, inspect existing studs, bolts, and nuts before beginning the repair. The flanged design supports direct replacement on the listed applications.
