i have just purchased a tornado downpipe with a sports cat,have been told the egt probe goes in the downpipe or you can block it off and fix it to the outside with no problems?
is this correct as i dont want to run the risk of cel lights etc
cheers
tim
p.s. new to subarus so be gentle

 

yes either or mate as its only the exhaust gas temperature sensor wont do no harm out.

 

good good, so it is fine on the outside as i thought that would be dodgy? now o gotta get the ****** out....any tips?i know its already rung off.

 

soak it well for about 20 mins with penitrating fluid and get some mole grips on it if its rounded already mate

 

just to check again,which is the sensor near the cat on a 96 wrx?

 

3 or 4 wires is O2/lambda, 1 or 2 wires is EGT/cat-on-fire.

 

really? its the wires going to it?

 

on a 96 the lamba is up top by the turbo,you can see it when under the bonnet mate.egt is just behind on down the down pipe and as stated 3/4 wies means it the lamba and 2 wires is egt and that is wires going to the sensor.

 

its a little confusing as i have been told the hole near the cat on the uppipe is lambda?? so thats wrong? its just that the new cat uppipe has two holes for sensors the one further back has been blanked, so the egt one is defo the other one?

 

just so im on about the right car your's is a 96 mate?cause on 96 model the lamba is in the down pipe.

 

yes mate 96 n reg wrx import

 

Sounds like you actually mean the downpipe there, as classic up-pipes never had cats, and would be too short to fit 2 sensors on. The lambda will be the one near the top, between cat and turbo, and the EGT will be the blanked one, at bottom near join with center-pipe.
