Well after running the exhaust for a few miles it wasn't quite loud enough for me. So sent it back to Rich at Austin Racing, within 24hrs he cut 50mm off the can (now 200mm long) and fitted 50mm internals. Kudos to the bloke, he really listens to his customers.
I loved how the Zx10 had a wide open air intake, a bit of searching and I managed to source a Hotbodies 2 piece bubble double screen with open beak.
A few more panels and it'll be off to be sprayed.
another bonus when searching the standard parts box in the loft, I found a set of standard hoses in a HEL box, which means mine have been replaced with braided lines, no wonder they're f**king lethal lol
