        only prob with that mate is MOTs

        my mate did it on his WRX and it failed, so he had to bolt one in for a day once a year! Lol

            I believe the parameters are narrowed i.e. the second sensor is allowed to report a reading much closer to the first sensor.

            With a decat the second sensor will essentially have the same reading as the first.

                    Basically what I am saying is CS will allow the secondary sensor to report back the same reading as the first as with no cat they will report the same reading.

                    The 1st sensor is used to control the fuelling in closed loop so CS may even do away with the second sensor. If using the likes of a unichip you could peg the second sensor to report back the same reading no matter what and keep the ecu happy.

                    Best talk to CS before removing but it should be fine

                        They must simply ignore the output from the second sensor altogether then or program it to return a value which won't bring on the light.

                              if you was to decat a scorpion exhaust that may hit the nail on the head for perfect sounding system too. (decat a piper and i think the police may want to have words with you for noise pollution lol)

                              Obsessed is a word that the lazy use to describe the dedicated!
