Which ever ones goes on your car!!!

Think the hole is for exhaust gas temp (lamda is in the down pipe IIRC). Best check your car and purchase the appropriate unit....not all have them Spec 1 vs spec 2 GTST etc....

Someone may come along shortly and shot me down but think i've got my facts stragiht :)

The EGT sensor sits in the original cat and some de-cat pipes have a flange welded on to fit the sensor. If the price difference ain't too great for your wallet then obviously best to keep the sensor.
Worth checking you can remove it from the old exhaust first as the last one i tried was impossible without irreparable damage. If you can remove and don't go for the de-cat with a flange then just poke it up through the floor or unplug it under the seat.
