    I believe all the new SRT's have it. There are "flapper" valves in the exhaust. To reduce drone during cruising they stay relatively closed, but when you stomp on the accelerator, the open fully.

    There are two valves in the exhaust that make up the active exhaust system. The exhaust system is on the 2015 R/T Scat Pack (392 hemi), SRT 392, and SRT Hellcat.

    When I was at Doge Rocks Gas Monkey Live last weekend, when the Hellcats raced, then turned around at the end and came back, you couldn't even hear them come back until after they were past you...VERY quiet when not in WOT. I'm sorry, but I don't own a quiet vehicle...my Harley is loud, my F250 powerstroke (5" straight pipe exhaust, not muff's, no kitties) is loud and my SRT8 Charger is loud (resonators removed, 3" 40-series (the old kind before Delta-flow) mufflers dumped at the rear axle). I want it to rumble at an idle, like my Charger. I don't mind the drone on the highway, that's music to my ears in itself...that's what the 18 speaker sound system is for if you don't want to hear it. I want mine loud...ALL THE TIME. So I'm going to do some exhaust re-engineering after I get mine...may have to eliminate that active exhaust and go old school on it...

    The Corvette ZR1's have a similar "flapper" in their exhaust. I bought an electronic bypass for mine which could be activated by using one of my three garage door opener buttons. I'm sure we'll see the same kit available for our Hellcats.

    I believe it is controlled via a dedicated fuse and if you remove the fuse, it stays open at all times. I'd have to research which one but read something about that a month or so ago.
