      Sounds amazing! However...

      The discription says that this pipe doesn't need a tuner, however it does. The PCM on my 2011 f150 boost will not read the levels accurately causing the Check Engine light to stay on with the same Cat codes as Before. Was hoping I wouldn't need a tuner. But they do sound amazing. Install is simple if you cut the existing stock pipe off. Otherwise you will waste 2-4 he's trying to take things apart for no reason. I rate it a 5 star because I fit perfect, sounds excellent and all it needs is a tuner for the CE light.
