All 2017 Dodge Challenger, Charger Hemi Cars Get Dual Mode Exhaust

In case you don't already know, you should be aware that the Tacoma area has a terrible public disturbance noise problem. I am mainly referring to the following: 1) Loud subwoofer thumping noises that are blasted through walls and into homes by vehicles and can be heard for several blocks. 2) Loud exhaust noises from vehicles with mufflers removed or with loud "sport" mufflers. 3) Loud sound systems playing inside homes that can be heard inside homes that are many houses away. 4) Fireworks exploded any random time, day or night, 365 days a year, even when no holiday is near. The people doing this are intentionally trying to harass and menace everybody in the community! This is criminal behavior and there is a serious lack of enforcement of the Pierce County Code Chapter 8.72. Loud subwoofers heard from 50+ feet away are illegal. Unmuffled or loud vehicle exhausts, are misdemeanor crimes. The law is very clear and explicit here. The residents of Pierce County do not have to accept this criminality! Please read the law and contact government officials, including law enforcement, and demand that the law be enforced! Loud low-frequency thumping in particular causes violent and explosive emotions in people. There have been many violent incidents and even killings, occurring here and around the nation, that were touched off by loud music being forced into people's homes. No wonder decent people do not want to move here, crime is high, property values are low, and criminals figure if they can get away with public disturbance, they can get away with any other crime. We do not have to accept this constant disturbance of the peace. It is illegal! The quality of life will remain low here until the residents do something about this.

Clips from the current version (2016/2017) of the Pierce County Code Chapter 8.72:

Seriously. Loud exhaust doesn't mean you are a criminal. Loud pipes can also save lives.

What I'm not too sure of is why when you race the Scat Pack engine while in Park doesn't soumd as loud when at similar RPM's in Drive.
Is that butterfly valve in the exhaust pipe "fully open" in both scenarios?
In other words, is that only Fully Open or Fully Closed?

I rented a 2017 Challenger R/T a week ago - and I HATED the exhaust note. It is so annoyingly loud that I no longer think about trading in my 2011 Challenger R/T on a new model. I'm not a young guy (I'm 55), so maybe I just don't understand what's so great about having such a loud car. I don't want or need to broadcast to everyone that I have a powerful car - I just want the power. If there was a way to order the older-style, quieter exhaust system for the Hemi, I would perhaps consider replacing my '11 model. Until or unless that happens, I'll keep happily driving my current R/T.

I Have The 2018 Hemi 5.7 And No One Seems To Be Able To Hear Or Want To Hear A Loud Loose Heat Shield Rattle When Those Flaps Close In The Morning During Acceleration !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Spring Loaded Actuator To Flaps Instead Of Direct Drive !!!!!! Sounds Like Shit !!!!!!!!!!!!!!!!!! Until They Open Then It's Just A Loud Exhaust......I Need Help Going Back To The Dealer Again For Someone To Look At And Now I Have To Rent A Car Because The Weekend Crews Say They Don't Hear It !!!!! Windows Down....Stop The Car And Then Go.....The Loud Rattle Eco's Off The Buildings And Into My Car And The Neighborhood ........Anyone Know The Fix For This.......Replace The Tailpipes ??????????????????

I have a 2017 Challenger R/T with active exhaust. Is there a possibility to switch it ON or OFF so that I can choose to drive around "quiet"?
I saw modifications to switch it to "always noisy" (additional wire harness to "fool the electronics") but nothing for "quiet mode".
