Aftermarket headers that only have 1 sensor bung are for OBDi vehicles. So in our case; 94-95 Celica's.
It shouldn't be a problem however if you do have an OBDii engine or 96+ Celica - you should just be able to take it to any decent welding shop and have them weld a second o2 bung lower down for you.
