The pipes will go on without cutting the bodywork.
Without changing our pipe's dimensions we really can't fit them without at least a little interference, and found that on one of the bikes we kept the left side lower in the original mounting position, but the right side lower needed spacing out about 5mm and dropping about 20mm. Another bike needed this spacing on both left and right lowers.
Strange that they should be so different, but I've seen so many differences in other aspects, so I guess it just depends on if all the production tolerances work for you or against you.
Try to keep the spacing as minimal as possible to retain ground clearance. However, it's unlikely that you'll suffer touch down issues unless you're on the race track. 3~4mm clearance seems to be adequate.
Moons ago when I rode the MC28, Harc-Pro gave me support and their pipes required quite a chunk cutting off the lower right side cowl to get good fitment. Upon asking they just told me that that's how it was.
I've tried as best I can to get the pipes as inboard as possible without compromising design, and this is the best I can come up with using the current spec.
One way around it is we could make the pipes fit the fairing, but then you guys might not be so keen on the idea of pipes that fit, compared to pipes that work. Well, that's my theory and I'm sticking to it.
In contrast, our TYGA bodywork is designed around the pipes.
