Here's a couple of more detailed questions (I have a friend trying to dump a Hawk (wife mandate) so I may have another one.

What kind of front end is that? Fairing stay for the 600rr piece? An since you have Rod's subframe and tail - what do you think about using a cored, stock ducati silencer with his exhaust? It will be for a street bike (that would have a 100% chance of seeing the track) so ideal power isn't an issue, I just think it would look better. Not a fan of the megaphone.
