2015 Dodge Challenger SRT Hellcat: Brutal Exhaust Sounds

After revealing the facelifted Challenger back in August at the New York Auto Show, Dodge took the wraps off the most anticipated muscle car of 2014 just a few days ago. Needless to say, the all-new Challenger SRT Hellcat roars and growls through its active exhaust system louder than The Who playing live at the University of Leeds in 1970, a concert regarded by music critics as the best live rock act ever.

When the first Dodge Challenger SRT Hellcat promotional videos were released on May 20th, exhaust sounds were also featured here and there, but those sound snippets were professionally recorded and edited in a studio. Fortunately, how the supercharged 6.2-liter HEMI V8 sounds like in real life is no longer a mystery thanks to the magic of user-generated YouTube content.

The most extreme production Dodge Challenger ever made is quite the machine. Apart from the aluminum bonnet that integrates a Viper-esque cold air intake and dual heat extractors, the inner headlamps feature integrated ram air intakes suppling cool air to the supercharger.

After lots of sucking, squeezing and banging from all 8 cylinders, the supercharged 6.2-liter HEMI V8 sends gases through a low-restriction exhaust system. It's an active one of that, featuring butterfly valves that stay closed at low rpms to limit noise levels. However, if you step on the gas pedal more firmly, those valves open to reduce back pressure and the staccato exhaust note's volume is turned all the way up to 11.
