which Lambda sensor position would be best ?
I have a 93/94 wrx jdm and my up pipe has been blowing for some time now so I have decided to replace it.
While I have bits off the car I thought I would port the headers while im at it.
Now I have noticed that the lambda sensor is in the drivers side header just where all 4 ports come together but the down pipe I will be fitting has a hole for the sensor. which hole would be the best the one in the headers or the one in the down pipe?

Although later on Subaru realised that many sensors failed in that location so they moved it to the downpipe where temperatures are not so extreme.
Your lambda sensor will last longer in the downpipe.
