The turbo noise is muffled by the factory intake. If you want more engine induction and turbo blow-off noises, you'll need to modify the intake. The problem is that the base engine (1.5T) can be pretty touchy with modifications (throws codes) and the 2018 and up Malibu 1.5T has a locked PCM and cannot be tuned to prevent that.
