Most of the reviews say the EXT is noisy...
The first is that this shock is noisy. There is an internal shuttle valve that makes a clicking sound every time the shock compresses. At first, I had thought the shock was faulty but discovered this is as expected and I no longer notice the clicking. I have been told the shuttle valve can be removed but it’s worth it for the performance gains so I would also recommend keeping it.

Back to square one. If anything, the knocking is worse now. I replaced the shock bushings and hardware, they were pretty worn out despite being barely ridden. I don't think it's a pivot bearing because I can't fell any sideways movement, and without the shock in they all feel smooth, however I've ordered some new ones just in case
On compression or rebound, whether with my hand on the top tube or sitting on the bike, there is a distinct knock which can be felt through the whole bike, even the handlebars. I've tried more and less preload on the spring, I've torqued the bolts up to spec. The damper feels fine cycling it in my hand, just smooth as it should be, and the rebound and compression adjusters all work as expected.
I don't think it's the check valve, you can hear that's a different noise when I put the lockout on
