You probably haven't disturbed your lambda sensor - I believe it's in the headers on a MY94 WRX...
What you're most likely looking at is the "cat on fire" sensor - it just displays a lamp on the dashboard and doesn't do anything in the ECU, so it's safe to leave it off.
The lambda sensor measures the exhaust gasses to allow a 14.7:1 ratio of air/fuel to be maintained when the ECU is in closed loop mode (ie off boost)

you will waste fuel.
You will be better off running the sensor if you can.
Am surprised that it is in the downpipe as as stated it should be in the headers at the collector on a car of that vintage.

As dnb says, its the 'cat on fire' sensor for a car of that age.
If you've got no cat, there's not a whole lot of point in connecting it to the downpipe.
