I am desirous of fitting a 4-2-1 extractor for the 407 because I enjoy low end torque and have even seen such items sold over the internet. However, I was told by the Peugeot service centre mechanic that whilst it is possible to fit that extractor, the electronic malfunction idiot light will then go haywire and constantly blink as if there was some electronic malfunction because this car's electronic is so sensitive i.e. being tuned for the original out-manifold. To what extent is this true? :blink1:
