Hey guys,
This is my first post - so I'm not sure I am asking this in the right thread. If not someone please let me know.

Anyway, I have this odd ticking sound when decreasing RPMs (around 1500-1000) and was wondering if anyone has heard this before, and what it might be?
I have no check engine light and engine performance/ power has not changed at all.

I have attached a video link to take a listen to. (The sound I am referring to specifically occurs after I revving the engine or slowing down)
