Maybe you can install them on the stock bar end (not using the provided ones)? If not you might have to remove the weights and drill a hole to install the new ones. It depends on size..
Having owned all three following versions:
-2018 Vit
-2020 Duke
-2020 Svart
I can you tell my Svart feels less powerful then the Duke I rode last summer.
I was so surprised that I felt maybe the previous owner somehow garbled the cylinder but seeing @Liteway 's chart explains it for me..
I've done the chamber delete as well but I mean, no chamber and no slipon.
I put a old exhaust tip str8 at the cat as a test:

It could sound good with a proper tip similar to this:
but I reverted to stock as its deafening loud..
Am gonna go next with Kenda K761 which I loved on my trusty SRX600 (17" also). Tried Bridgestone Trail wings with so-so results..
You do offroad or mostly tar?
Edit: A good review here:

So its 3"inlet. Man that chamber is heavy..
Tried an old exhaust cut up with some fiber packing in it and its close.
Will further experiment tomorrow..
Soo I took out my stock muffler and quite like the sound. Am contemplating a few ideas for a stubby exhaust which would add a bit of grunt and restriction.
Watcha think:
