Sounds more like an air leak. Make sure that everything and all of the hoses and lines are tight. It sounded loud right by the intake hose.

Kinda sounds like the bypass valve is fluttering.

You can try unplugging the vacuum hose on the bypass valve to confirm whether its that or not. If it is the bypass valve, most more than likely you have a vacuum leak somewhere that is causing the piston inside the valve to fluctuate.

Noticed under very light revs it does speed up the sound, but either disappears or gets drowned out by the exhaust by about 2k RPMs
