Active exhaust was introduced as an option on the 2015 Dodge Challenger SRT Hellcat and Dodge Charger R/T Scat Pack. It became standard on Dodge Chargers and Challengers equipped with a Hemi V8 engine in the 2017 model year. As a result, starting with the 2017 model year, the Challenger R/R, R/T Plus, R/T Shaker and R/T Shaker Plus trim lines, as well as the Charger in R/T and R/T Road & Track trim lines, are equipped with the same active exhaust as the Scat Pack and Hellcat models.
