Hey Canuman, I have an E model and had the Nomadic Rack, Justin is local to San Diego. It worked well. I eventually swapped to an S subframe because I bent my E badly in a crash haha. The S only required me to cut my rear fender and build a maybe a 1.5-2" bracket to bolt the pipe onto the frame. I didn't mod the airbox in any way. But, best of luck with the E racks, I'm quite interested to see how they turn out. Post some action pics when you're done.
