So today as I was driving the Z and I noticed a weird metal rattling noise, so I turned the radio off to pay attention to the noise created.

It was a rattling noise that sounded like it was coming from beneath me in the car, especially when I shifted into 1st and gave it gas.
It doesn't make the noise when I'm in neutral, or when I'm just sitting there.
It also made the rattling noise after shifting into 2nd at about 3k rpm.

Anyone know if this is normal?

Thanx!

 

did you do any exhaust mods?

 

Does it go away when you hold onto the gear shift ****?
