Perks I think in another post you mentioned you liked the stock exhaust although in another thread you mentioned you wanted an end can.
Just had an idea thats the best of both worlds and thought you might like.
The stock exhaust is pretty light and pretty much straight through design so very similar to a race can. If you removed the ugly, heavy cat where all the restrictions are you would have virtually a full system as the stock headers are full titanium large bore items.
A link pipe will cost you about £80, save about 5 kg, make the bike sound and look amazing.
These people are very good quality and price.

They also do custom work to your design but I'm sure they will have previously done a system and link pipe for a popular bike like the ten.
As they do custom work if you wanted you could ask them to weld a threaded boss onto the link pipe so you could still mount the OEM Kawasaki heat shield.
Hope the idea is of some use of not just tell me to shut the front door
