Why does my Ford Focus make a loud rattling noise when accelerating?

I recently noticed that my Ford Focus is making a strange rattling noise whenever I accelerate. It seems to be coming from the engine area and gets worse the faster I go. What could be causing this and is it safe to continue driving?

It sounds like you may have an issue with your exhaust system. This can be caused by a loose or damaged muffler, exhaust pipe, or catalytic converter. I recommend taking your car to a trusted mechanic for a thorough inspection.

Another possibility is that your engine is misfiring, which can cause a rattling noise. It's important to get this checked out right away to prevent any further damage to your engine.
