The extra holes are in front of the cats. They are for wide band O2 sensors, which let you monitor the air/fuel ratio. The one on the passenger side pipe would be used by a tuner on the dyno. It stays plugged otherwise. The one on the driver side would be used if you have an AFR gage. I used the PLX and DS trinity to monitor/log AFR. It can be plugged also if you're not worried about your AFR.
