My Corbin Gunfighter seat is on it's way from sunny California so here is the first pic of the stubby exhaust and pillion peg brackets gone, I am hoping that the exhaust will be ok without the hanging strap as it looks neater without it, I had it made with a 60mm inlet so it uses the factory sealing ring and clamp, it also has a removable baffle as I didn't want it too loud.

The can creates a long "moment arm" that will exert quite a bit of force to the coupling joint. Every bump or change in direction of the frame will wiggle the can exerting force on the joint and connecting pipes. It may look better without the straps, but it will sound much louder when it breaks off.
 
Good point John but the can is very lightweight and there is a sturdy looking bracket just in front of it under the gearbox, but I think I will end up making up a link probably from the bottom pillion bracket hole.
 
I must stop spending money now, do we ever?

From the third (bottom) picture in your post above, I would say that the mounting strap that you have bolted up to the heel plates would provide ample support to negate any undue stress on the mid-pipe mount, but I'm no mechanical engineer.

could you supply details about the can you used?

It came from A16 Road and Race here in the UK, you can order from their website, the can is an oval stubby in carbon fibre with c/f outlet, it has removable baffle so is not too loud, the inlet size is 60mm and fits straight onto the mid pipe, the cost was about £200.

I really would advise you to put a strap on that can. Every bump will put stress on the joint, irrespective of how good a clamp you have sealing it. It only serves as a fulcrum and eventually it will crack around the inlet to the can. I`ve had this happen with a titanium can,(repaired under a lifetime guarantee), even though it was supported by a strap, but because the strap was only a third of the way up the can it flexed until it cracked. I now have 2 straps on the can and it`ll now outlive the bike. Yup, a bit belt and braces, but I don`t like having to do the same job twice.
