I have a JBA cat-back for Chrysler and Charger. It's an American company known for its headers. It fits new and old models. The sound in the clip is without mufflers. The cat-back is installed on a 2018 Chrysler 5.7. Whoever wants to hear its sound, contact me on WhatsApp only. + Chrysler and Charger muffler delete pipes. Location: Al Ahsa
