WHEN I REV MY MOTOR IT RATTLES?

2000 Ford Mustang • 186,000 miles

My 2000 ford 3.8 mustang v6 5 speed manual rattles when I start my car and leave it in park/neutral everything is fine but when I rev my motor it rattles?

Basically when my car gets to 2000 rpm it starts rattling but from under neath the car I changed the motor mounts transmission mounts clutch flywheel oil change in both motor and transmission when I rev it with the hood open you don't hear a noise so I no its not the motor its sounds more like somewhere around the transmission area?

It may be a catalytic converter heat shield. See if rivets have broken off.
