What sound am I hearing in this video.

Well Idk what it is though it was cat then DV but now I don't know. Its only when I first start the car and lasts about 30 sec before I don't hear it anymore. Listen to the end you can hear it better.

It still sounds like it could be the DV, but it could be a torn vacuum line or a boost leak as well. You should do a pressure test to check and see. If youre still on your stock DV, theres a good chance its just not holding boost that well anymore, or is developing a tear.

my guess would be a boost leak as well but it's hard to hear... and I live like 15 minutes away from perkasie btw

Thats cool but I got a boost leak tester so Ill see if that could be it and ill check the dv. seems odd it only happens for about first 30 sec of driving though.
