i installed a new header today and the bung for the o2 sensor is in a bad spot. for one thing it doesnt reach because the bung faces straight sideways out of the collector pipe. also, it points at the transmission so it would be tight anyways, even if the wires were long enough. what should i do? will a muffler shop be able to weld in another bung in a better spot for me? theres plenty of room.
