Quick update...
The pipes fitted like a glove! Excellent. Hardest part was removing the existing standard unit - had to loosen the front down pipe to facilitate.
The pipes run well clear of the Centre Stand, and when the whole thing installed, it looks like a quality product that was engineered for the bike.
Downer - the pipe clamps were just too small to fit, and have had to source new ones.
The baffle fits at the beginning of the box, and is really easy to take in and out (remove mounting bolt and unclip spring.
Mea Culpa. I didn't record the sound of the original on a run - only stationary.
I forgot to photograph the stages of install, but in fairness it is very straightforward.
I will take it out and get my partner to record a run with baffle in and out. (I have a feeling that it will be too loud without, and may even need a tail pipe baffle as well - we shall see).
Oh, anyone need a really good condition standard exhaust system? No scratches/dents etc...
