The noise is coming from under where the exhaust system is. I'm not really sure what it is, but if I turn on my Ac and the fan turns on that's when it goes louder. When I accelerate the noise goes away but quickly comes back after I stop accelerating. If the AC is off the noise is still there, but not as strong. In the video, the AC is on. When I changed my oil, the noise went away. But it's back now after 1.5k miles.

What can I do to fix the problem?

 

sounds like an exhaust rattle

 

Well yeah I know that. But I need to know what is exactly causing the noise and if I'm going to need a new exhaust etc.

 

Did you check the catalytic converter heat shield?

 

it's your transmission hamsters man. they're dying.

 

Yeah, that's where the noise is coming from.

 

so whats the solution?? should you take it off??

 

i have almost the same problem...whenever my clutch is out and in neutral just idling or while under load it makes a weird almost rattle...but when i push the clutch in the noise goes away...i had the clutch replaced less than 10000 miles ago...could it be the guy did it wrong? i am only posting this question here because it will not allow me to make threads on my own...as i am a new member. any comments or advice would be great.

 

it's hard to take the shiled off because it's all welded together :/ If you have a plasma cutter you could get rid of that shield like presto!!
