I am attempting to fit my downpipe at the moment (MY95WRX) and am having problems removing the old Lambda sensor from the old pipework. I have tried everything to remove it, including the old blow torch method. Basically its just seized up with rust and will not budge.
There is a hole for it in the new downpipe I have.
QUESTION:-- Do I need the sensor in the new pipe or can I get away with just blanking off the hole. ?
