    4.8 extractors with 4 O2 sensors

    Has anyone fitted extractors to there 4.8 with the 4 O2 sensors?
    Did you get any engine lights? and are you happy with them?

    I bought A complete system from Beaudesert exhausts, Ceramic coated Extractors, with High flow cat and 2.5inch stainless pipes.
    Has some adapters for the bottom O2 sensors, that should prevent warning lights.
    When it is fitted, I will test and report back.

    Exhaust system is fitted, quite easy to do, everything fitted up perfectly and looks to be very well made.
    Driven about 300km so far, no warning lights, a bit more responsive and overtaking seems a little quicker, too early to tell if the fuel economy will be any different.
    Only one slight negative, there is a little bit of droning at highway speed, not excessive but I can notice it, but it does have a nice deep note to it.

    Shoulda done a before and after dyno. My RB got a 10% increase and picked up better mileage, with headers. A big deal for a little motor. It would be very interesting to see if yours has made a real difference.
    My advice is: not to follow my advice.

    Dyno run would have been nice, Just don't have time at the moment.
    At least we have a solution for other owners of the later 4.8, with 4 O2 sensors
