Installation Notes

Verify the vehicle’s emissions label and match the California EO number D-798-9 before installation. Confirm rear-position application, flange style, and overall length against the original converter. Because this converter has no O2 sensor ports, transfer or retain any vehicle-specific sensor arrangement as required by the application.
