Plug the second lamda hole in the decat with a bolt..... keep the second probe plugged in, and tape it up out the way under the car. My cup was running like that for two years with no lights

Cheers, would only remove it because it sounds like its full of spanners and the cost of a replacement. out of interest did you notice a change in perfomance? where would be the best place to purchase a bypass pipe from?

It certainly revs more freely. I got mine off a chap from here, but check the usual, k-tec yozzasport etc
