it happens only while driving and I would say in speeds less than 60mph. when I am parked there isn't any such noise. I kind of reminds me the noise of the heatshield but I removed it (the exhaust one). It's more like there is something flapping due to wind. Engine still runs good and strong (<100k miles).

Any suggestions? I will take it to a mechanic soon for some other things and ask him to check whether anything is loose down there.

werd, but unfortunately I don't have any tools. However I have some local friends that might be able to help. Just wondering about worst case scenarios.

I doubt its anything serious.. Unless you can feel it. Then you might wanna get it checked out.

probably your plastic fender liner that extends toward the front bumper came loose.

Or if you still have the oem black plastic skid plate/diversion panel it could be loose and flapping.

Good luck!

yeah, my fender liner/plastic panel under the front corner of the bumper came loose and sounded like I spun a bearing.

Glad im not the only person that thought that

@ OP, like the other guys said, something is most likely just loose.

maybe it serves the fapping... oups flapping I meant. A nice 240 doesn't constitute a thread jack, maybe a free post -like this one.

p.ex. at 0:35. that metallic sound. It is louder when moving, but I just can't record while driving.

Are you sure it's not an exhaust leak? That's what mine sounded like when my AIV plug fell out.
