From what I understand the MST intake is one of the loudest intakes for the G platform. You might not be able to hear it from inside but I bet it's noticeable from outside the car. Don't forget the ASD is not just for fake exhaust sound it also does noise canceling. Also that's amazing seeing a Z1 in person in the US.
I love it.. I don’t regret it at all..2024 has a couple new colors available and honestly I still would go with this blue.. Also the attention it gets is unmatched..😬👍🏾😬
