My WRX STI Version IV Type-R Coupe has 2 lambda sensors, does anyone know if other imprezas have them also? and what do I do, as my hks hiper does not have a hole for it....

HI rob here, the sensor near the bottom is not a lambda sensor, it's a CAT ON FIRE warning sensor, and puts the light on the dash if the cat gets too hot, its the one that looks like a grill pan symbol on your cooker, that comes on when the ignition is turned on and then goes out when you get the engine running,simply diconnect the sensor as it is no longer needed as the CAT has gone, and fit the downpipe as any other model and hey presto job sorted.
