Installation Notes and Tips

Fits 2012-2015 Chevrolet Captiva Sport, rear. Confirm the vehicle’s emissions configuration before ordering, since the fitment notes specify federal and California emission models with state restrictions. An exhaust gasket is recommended, and additional part 31652 is listed as needed to complete installation. Verify the inlet and outlet connection style, overall length, and converter position against the original unit before installation.

Quality Assurance

Walker’s EPA line is built around direct-fit replacement geometry and emissions-focused application coverage for OBDII vehicles. This converter is not CARB certified, so it should be matched only to the listed federal-emissions application and local regulations.
