When under heavier throttle, usually about half and past, I start to hear a very pronounced metallic sounding rattle from the front left of the car, but it's completely fine when driving easy. Could this be a failing transmission mount, or CV joint? Any thoughts?

It sounds more like pre-ignition.

Try some high octane gas and see if it goes away.
