Yeah I saw the video was old, and they have nothing for F's on their site, so I figured not. Just researching so I can throw everything on mine at once when I get it. Thanks man.!That clip has been around for quite some time. My recollection is that someone asked them, at least about the exhaust, and they indicated that they would only proceed with the development if that had something like 30 or so firm orders. So, I guess, AFAIK, the answer is no, Greddy has done nothing with this.
