Why does my Audi A5 have a strange noise when I accelerate?

I recently noticed that my Audi A5 makes a strange noise when I accelerate. It almost sounds like a hissing or whistling sound. Is this something I should be concerned about? What could be causing this noise?

Hello Bradley, it sounds like you may have a leak in your exhaust system. This can cause strange noises when you accelerate. I would recommend taking your car to a mechanic to have it checked out.
