Hi Frank, You are right to say that these mods will work on a 790 as well and there are certainly more of them out there at the moment thats true. The 790 is an easy motor to unleash impressive gains with by simply adding our pipes, the 865 however is less so hence our attention to it. My point is that for the big gains in performance the 790 doesnt NEED it whereas the 865 kinda does for big improvements - and noticeable they are, watch this space....
