I just wanted to let everyone know this is a nice kit. Very simple and cost effective. Of course you could use some uni vents and jet it too, but our Predators are to nice to treat like that. One quick note, the kits supplies all hardware needed. The one thing that I would like to see improved is the use of jam nuts instead of standard nuts.The installation is under the filter which makes it safe, but I still used locktite on the threads. This is the biggest power gain for the money. I now understand what everyone means when they say this bike likes to breath.
