Default New (used) car... does this sound normal?

Hi all - I just bought a 2011 WRX with 50k on the clock and a few mods (Perrin CAI, TurboXS BOV, TurboXS catless DP, Perrin catback, and a tune using AP2). It's my first turbo Subaru (my previous car was a 97 LGT) so I'm getting used to driving a turbocharged car and having fun with it, but I'm somewhat concerned by a particular high pitched sound coming from the engine bay that I'm not sure is normal:

Is this normal or does this sound like a boost leak possibly? Or a turbo issue maybe? Thanks!

Sounds like a boost leak.

Thanks guys. The strange thing is that the car has been overboosting as well. I may be wrong, but if the car has a boost leak, wouldn't it be producing less boost rather than too much? The first day I drove the car and stepped on it in 3rd gear, it hit 20.7 psi and I got fuel cut with a P0244 CEL. I assumed that it was due to the cold temperature (~30 deg ambient), but then yesterday, again in 3rd gear, it hit 22.3 psi, but with no fuel cut... either way that is way too much boost for this setup so I'm concerned. According to some reading I did on here, it may have something to do with the catless DP on the car.

Thought you couldn't make full boost with a boost leak but maybe I'm wrong

Possibly a boost leak, ive never heard one though. If you have boost creep you really have two options. Get rid of the catless downpipe, or get an ewg. Lots of information on this site and others. Use the search.
