Actually I think most of my objection to the standard cruciform is the external seam which looks a bit 70's Honda-ish to me, and it's hard to polish in the dimple.

But although it (must have) flowed more freely due to the bigger bore it still noticeably blew harder out the right pipe than left - perhaps more so? I have since replaced it with a Spaghetti style crossover (from Madasl) which is definitely better flowing, plus at 45mm it's 5mm oversize; I meant to get to the dyno to get things checked but never got round to doing so but it's definitely an improvement.

Yep replaced mine too with a pre-Ducati Performance, Gio.Ca.Moto set of front pipes bought new old stock years ago.
Not quite as intricate as a full spaghetti system but a much less restrictive join. I'm not sure what the gain (if any) might be on this but the long since unavailable Sil-Motor spaghetti system used to quote a 5bhp gain all through the mid-range on a 900 motor.
