Catalytic convertor

Does anyone know what sensors go into the standard cat on a 20vt? is it an oxygen sensor and a lambda sensor? I have just got a turbo revs decat pipe and want to know which sensors go into this one?

Oxgen and lambda are the same mate
You've got a front and rear lambda sensor

Brown plug is the front one and black the rear one

OK ta, didn't know they were the same sensor!! do you know if the decat pipe has the 2 holes for the sensors to fit into? it looks like it has from it's pics, as its not arrived yet.

Yes it has the 2 holes for both sensors

You will need a spacer to space the second sensor further away from the gases to avoid engine management lights when using a decat, can be had on ebay for a few quid
