In ICE cars, some people remove the mufflers and modify the exhaust for louder and more deeper sounds.

I'm aware of that. We're talking about artificial engine sounds, though.

I'm not a motorhead, so I only skimmed second hand part offerings and found this: OEM Maserati part number 670006946. For optics it's advertised as noise cancellation system, but owners' forum [0] suggests it can work either way. They also discuss a defeat mechanism.

That’s because it’s a microphone with a speaker playing the inverse wave form.
