I love this package! I got the barker full exhaust, Msd blaster, and FCI without box. The power gain and throttle response is unreal! I haven't come across any other YFZ that can touch mine now. Kenney at KB Motor sports was immensely helpful throughout the whole process. The barker and the msd blaster shipped really quickly. However, since the Fuel Customs Intake comes from California, it took quite a long time. Almost a month. But well worth the wait! One thing i must warn you about is how loud the barker is!! Sounds awesome but just soooo loud! I bought the silencer core but haven't had a chance to put it in yet. If you have a dB limit where you ride, it will definitely be over the threshold. Overall it is a massive power gain without tearing into the engine.
