Post-Catalysts (Rear) Oxygen Sensors should be mounted in the provided locations in the catalyst assembly. It is highly recommended that the Oxygen
Sensor bosses in catalyst assemblies be used without modification. If they need to be moved or mounted differently to fit your vehicle, the sensors need
to be mounted the same distance from the rear of the front catalyst's brick/honeycomb as the unmodified catalyst assembly. The oxygen sensors should
be mounted with the sensor tip pointing between 10 degrees above horizontal and fully downward – do not mount with the tip oriented upward.
Modifications to the exhaust system are likely in order to fit your particular vehicle. The provided front catalytic converters, must be mounted between
16" to 20" (as measured along the path of exhaust gas flow) from the closest cylinder head exhaust port face. Rear oxygen sensors should angle toward
the center of the vehicle.
