Weird rattle sound when depressing gas pedal...
hi guys-
im trying to diagnose this rattle sound. I can reproduce it when I'm depressing the gas pedal when parked- right around 1000rpm-1500. Also when driving at slow speeds, up to 30-35 mph, similar sound happens.
Any ideas? No performance loss or anything.
Thank you in advance...

I had a video just couldn't upload for some reason but it worked from my phone....
rattle noise is obviois and starts around 9/10 seconds into the video, did it twice in video.
im wondering if it's a heat shield or something ever since I got my secondaries and res deleted maybe the heat shield is hitting one of those just a guess...

When I press the gas medal around 9 or 10 seconds it rattles.... then again around 14 seconds another same rattle- I feel it is def some sort of shield rattle around the exhaust system somewhere. I may have tonjust raise the car up and check the entire system. I'm hoping that is the case and it's nothing else.
I can hear hear it in video- not sure man

Ok man then have at it, it's probably an exhaust shield then if you think so. Good luck.

I hear it.
Definitely sounds like something is loose under there.
Hopefully you'll be able to trace the issue with the car up.

I have a lot of weird sounds. Squeaks, squeals, whining, knocks, rattles, rubbing, vibrating. Car still drives fine. I just turn the volume up or step on the gas. No "issue" here.
Listened to the video again though. Sounds exactly like either a loose exhaust shield, or possibly exhaust vibrating against that center crossmember.
