Right then

99 STI JDM V5
Strut brace off
intercooler off
heat shield off
skin from knuckles off
everything wd40'd in prep for tomorrow morning when i will attempt to remove the down-pipe to fit the de-cat scoobyworld H&S downpipe.

QUESTION...........are you ready?

Is the sensor currently in the cat on my car a heat sensor only (thus not necessary after removal)

or is it required for fuel/air/ratio mixtures and ultimately will cause me problems without?

Thanks peoples

sensor at top is lambda
sensor at bottom is cat fire

bottom sensor is not needed, ive ran the cat fire unplugged for about 6 months with no problems

 

i haven't seen more than one hole for a sensor, the only i can see is directly begind the turbo and the H&S downpipe has a hole cut for this. Which one would this be?

Lamda required right?
