You should of replaced both your UP and DP gaskets with the OEM-style gaskets.

Willing to bet it's a pre turbo leak.

rollin on 17's now and they're dirty

have you checked for leaks?

One easy way to tell if your UP or DP are leaking at the mating flanges is to see if you have any black exhaust carbon coming out at the flanges where the gasket is at.

Or pressureize the system.

Did you already check visually to see if you have any black carbon coming out of the mating flanges?

silv03wrxwag is an unknown
I had the same sound on my '03 wrx wagon anddd I got the news that my turbo was dead. Does the sound happen when you hit the gas, gets louder the higher the RPMs go and goes away when you let off the accelerator? if so, it's the turbo. I thought it was an UP leak but unfortunately it wasn't . good luck to you though.
