In general, the longer the O2 extender is, the less likely it is to throw the fault/light (the O2 has a longer path to travel to the sensor). I don't think it is really brand specific as much as the design/length of the extender that the O2 sensor plugs into. Really, if you are running test pipes or LTH, you should get a tune. As mentioned, UpRev (and Cobb) will allow you to turn this fault off altogether, and you will be able to take full advantage of the increased breathing.
