ticky

I have recently purchase a o/p d/p for my95 wrx ra. The d/p has a thread hole near the turbo end which i believe should be blocked or blanked off (02 senor connections)The only problem im having is that there is a small sensor at the bottom of my original cat d/p. What does this sensor do? Do i need it? There is another sensor connected to the exhaust manifold near the up-pipe, I think thats my lambor sensor?
Anyway this small sensor has stopped me from fitting my new d/p. Please help

its just a cat temp sensor and as far as i can remember it just operates a light on the dash...

I think you need a lambda blanking cap. the lambda sensor is on the down pipe.

The sensor in the up-pipe is lambda, the downpipe one is cat temp sensor. I think Scoobysport sell blanking plugs for tha cat sensor in the Scoobyshop
