    Active exhaust valves. Those control engine noise mostly and are fully open at wide open throttle. You might get an engine code with them disconnected.

    Check out 1:15 in the video below.

    Did you fire it up with the exhaust off? If so a video would be nice

    Thermal R&D in Lancaster CA has just finished developing a 3" stainless cat back system with Helmholtz chambers that replace the rear mufflers, this will get rid of any drone. They ran the car on the dyno this morning and picked up 14 hp and 67lb ft of torque! We are working on getting the check engine light off so that will have to happen first before the system will become available for sale but keep an eye out, this will be the cleanest best sounding system on the market for all you Hellcat owners! We will post videos with sound clips as soon as we can.

    Very nice metallurgy there. In the meanwhile since you said they may go for sale, could you have the owner of the shop contact our admin cereal killer to sign up as a supported vendor? That needs to happen before any sales happens on here when that time comes. :)
