Here are my just installed FMF's, though the video/audio created by my camera isnt as high quality as yours I dont think. They dont sound quite as loud IRLF as they do on this video, but they are pretty freaking loud. Not earplug needing loud, but you definately know something bad has just cranked up. I made this video before I let it idle reset, and the first time I hit the throttle it died, which made me laugh so much my finger came off the camera button, thats why its split into 2.
