3 minute 40 seconds in but it appears throughout the track.

Anyone know how they pulled it off technically?

Serious answer: If you mean the repeated 'schloppy' noises, I think it sounds they probably applied some kind of resonance/cutoff filter to exaggerate the peaks of the percussion (or samples of it?) into the odd sound you hear. That would be my guess anyway.
