Default Little help with a noise from the engine..

Not sure this belongs here but oh well...
A little background. It's a 2000 RS with a EJ20K swap. Stock turbo, stock intake, stock downpipe.

When I accelerate up past 3-3.5k rpm, I get a weird "whomp" sound. This is my first turbo car so I'm not familiar with this. I know the "whoosh" of the blowoff valve, but this sounds like something else. For anyone more familiar with N/A motors, it's similar to the sound of an aftermarket intake.
Anyway, it comes on and off really quickly depending on how fast I rev past 3k rpm. But if I can hit the throttle just right, with the right amount of load, I can almost prolong the noise until it's almost like a hum.

I've been told it's the sound of the wastegate. Can anyone confirm this?
Also, I had an Apexi cone intake at first and I thought that's what it was, but I switched it to a K&N panel filter and it seems like it's quieted down a bit.

Thanks in advance.
