Hi there, So about a week ago I bought a 2005 Lgt wagon in a stickshift from this guy who took really great care of it and its been super fun, the car was bone stock when I bought it, the owner before the guy I bought it from put a Cobb accessport into the car and the guy I bought it from never really even touched it so it was on a stock tune, well about a day ago I went stage 1 on the car and did a muffler delete but that's all that's been done to the car. So about halfway home from my trip to get the car (about a 2 1/2 hour drive) me and my dad noticed this weird rattling type noise, I just chalked it up to an exhaust rattle and drove it normally all week, But me and a friend were doing the muffler delete yesterday and dug deeper into the sound and realized that it seems to be coming from the turbo, The weird thing about it is that it only makes the sound when the car is fairly cold and when I'm low in the rpms, it goes away when I'm on spool and after driving for 5-10 minutes my friend suggested a turbo bearing but i wanted to get someone with a little more experiences advice.
here's the link to what it sounds like:
