I do not have dyno numbers to back me up but the K&N Typhoon seem to perform the best and are easy to install. I did not want to hassle with the bumper so I didn't go with a Long Tube route like the Stillen G3. The K&N Heat Shields are pretty good I like how they utilized the stock box mounting holes for the heat shields. It’s just a very well built product and sounds amazing. The Dropins + Smooth tube work well but I felt it still restricted intake air flow. The K&N Cone filters just flow better then the panels.
