If you are installing the J pipe in a 1985 or earlier Vanagon and do not have a catalytic converter with a port for the oxygen sensor, you may need to weld in a port somewhere. We weld this bung into the converter and on the late Subaru engines that have two O2 sensors, end up with one in each end of the cat.
