All 2017 Dodge Challenger, Charger Hemi Cars Get Dual Mode Exhaust
When the newest Dodge Challenger and Charger were introduced in the new Scat Pack and Hellcat trimlines, they were equipped with a 2.75 inch dual mode exhaust system that allows the two Hemi engines to scream when being driven hard while being a little quieter when driving the gently. This system gives owners the high performance roar when pushing the Challenger or Charger to their limits, but when you have your car idling in the driveway – it won’t wake the neighbors a few houses away.
The sound of these exhaust systems on the 2015-2016 Dodge Challenger and Charger Scat Pack and Hellcat has become one of the favorite features among owners (after the raw power), but those folks buying the models with the 5.7L Hemi V8 have been forced to turn to the aftermarket for a similar roar over the past two model years. That changes for 2017, as every new Dodge Challenger and Charger with a Hemi engine will have the 2.75 inch dual mode exhaust.
Dual Mode Exhaust for All 2017 Hemi Muscle Cars
During the 2015 and 2016 model years, the 2.75 inch dual mode exhaust system has been standard equipment on the Dodge Challenger and Charger in R/T Scat Pack, 392 Hemi Scat Pack Shaker (Challenger only), SRT 392 and SRT Hellcat form. So every car with the 6.4L Hemi or the supercharged Hellcat Hemi have had this exhaust system for the past two model years and when the 2017 Charger Daytona 392 hits the market with the 2017 Challenger T/A 392, they will also have the dual mode exhaust system.
The big news here is that the 2017 Dodge Charger Daytona and the 2017 Dodge Challenger T/A with the 5.7L Hemi will come with the 2.75 inch dual mode exhaust, and this standard exhaust system on these performance packages will also be standard on the other 5.7L Hemi models. This means that the Challenger in R/T, R/T Plus, R/T Shaker and R/T Shaker Plus trimlines and the Charger in R/T and R/T Road & Track trimlines will get the same lovely-sounding exhaust system as the Scat Pack and Hellcat models.
How the System Works
The dual mode exhaust system in every Hemi-powered 2017 Dodge Challenger and Charger uses a pair of electronic valves located near the rear of the vehicle to control the level of the exhaust noise. At idle and in light throttle situations, the valves are in their closed position to keep sound levels down. This also helps to reduce “drone” when cruising on the highway, but when you put the hammer down, the valves open and the exhaust gets a whole lot louder.
When those valves are open, we get the beautiful roar from the Scat Pack and Hellcat Challenger and Charger, and while the 5.7L Hemi will have its own sound, it should be a great deal louder when the 2017 models with this new active exhaust system hit the street.
I am driving a 2016 Challenger 392 Hemi Scat Pack Shaker with the dual mode exhaust right now and I love how the system works – and how great the car sounds at wide open throttle. Adding this exhaust system to every Hemi model will most certainly increase the cool factor of the dueling Dodge muscle cars.
