Honda fit 2012 fluttering / clicking on drive

Not sure what this is, if it's unsafe to drive etc.

Edit ; Seems fine as when moving it goes away but sometimes on accel it almost has a metal ring? Like something is being hit?

Check the spark plugs. GD and GE Fit's have a very common issue of liking to eject spark plugs at over 100k miles. That sound could be one coming loose.

Other possibility is a heat shield. There's a heat shield on the exhaust manifold that can come loose and cause a rattle.

Think you need to do some digging.

Appreciate the response. I'll see if it's something simple like that.
