just fitted new clutch and decat front pipe today does anyone know what the small sensor is for that goes in the original cat i know the top ones definately a lambda sensor the bottom one looks like a heat sensor ? maybe just wondered if it is needed as there's no hole for it in the decat pipe and left it tied up underneath hasnt affected anything yet cheers
I think its a heat sensor as well. The diagram is a little misleading, IIRC yours is same as mine, cat wise, only cats are in downpipe and centre. Which r no longer there.
my97 wagon feels a lot more responsive plus noisier you can hear the turbo and dump valve clearer now well worth doing not sure whats next though chips maybe
