Default HELP! Strange Noise from the boost...

Hello to all, I have an Audi S4 2001 with K04s, Miltek DP, Cats and Exhaust. The car is very nice, but this weekend I started to notice some noise like a leak or something near the 4k rpm.

Could that be my Y boot gone (Never changed) or the diverter valves ?

Thanks in advance!

Default does it sound like a blow off valve sound, or a 'whooshing' sound?? if it's whooshing at high RPMs

check the throttle body boot - it's really easy to get off and on, and only $12 to replace unless you go with MTM, Samco, or etc.
