Tip In Knock?!

I've read around about the issues of the 'Throttle tip in knock' sound that some of our cars get, but had no fix/solution to stop it from happening again.
No engine/power mods on the car, and before when it was completely stock I still had the same issue? Just wondering if there's anyone that had this issue and got it resolved. Thought my Oil Change would change it, it did for a bit then it came back.

Happens when I'm coasting then I start re-applying some throttle and it'll come and happen for a few seconds then it stops.

Went twice to double check if it was my heat shield and it isn't, so this is almost what I come to the conclusion of.

For those who need a auditory understanding, here is something almost identical to mine.
