just fitted a decat down pipe and noticed i don t have a lamba sensor on my 93 wrx is this needed? On the old pipe some 1 welded it up lol. Oh and now i got a full decat system will engine light come on
the lambda sensor should be in the headers as std the one in the standard downpipe is a cat sensor.just decated mine and had no check light come up. pete
