I also did a analog watch test. Only two of five cars I was interested in fully passed it. The BRZ and the Legacy, the rest of the nicer cars supposedly quieter failed. Watch test is when I am wearing the watch and the passenger and I can hear it tick loudly while holding 50 mph and idling. I plugged up the sound hole on the test drive.
I duno. Maybe something changed in 2017.

well heres the thing about the sound tube - again its a choice between enjoying those moments where your car can shine vs making it into just another car. so, our cars are not what anyone would call fast. so when you inevitably stomp on it to get it going the induction sound from the sound tube is about all you hear thats somewhat exciting cause the stock exhaust is so quiet. so when you plug it to make it comfortable for your commute then when you want to enjoy the car, you hear some faint sounds of work being done when youre trying to get on it and that's about it.
i only plugged my sound tube after i swapped the header because that replced the induction noise with better sounding exhaust noise.
