Configure your 2017-2020 Dodge Challenger for the sound you want, when you want it! MagnaFlow’s premium performance exhaust offering, the xMOD Series, provides an unrivaled exhaust experience! The revolutionary xMOD Series offers a completely modular exhaust system with all the benefits a MagnaFlow premium exhaust is known for: lifetime warrantied stainless-steel construction, dyno-proven performance featuring straight-through mufflers and fast-flowing mandrel bent pipes. xMOD’s core feature is the ability to configure your sound utilizing specifically engineered, interchangeable modules. Challenger xMOD Muffler Modules offer MagnaFlow’s proven straight-through core design with 5” round by 14″ long bodies, and now feature race bred v-band clamps for quick installation and removal. Easily switch from the deep, aggressive signature MagnaFlow exhaust note to the wild straight-pipe race car sound offered by the xMOD xTreme Deletes. xMOD xTreme Deletes for the Challenger come equipped with the same race bred v-band clamps which allow removal of the Muffler Modules for that xMOD xTreme sound experience. PLEASE NOTE: While xMOD systems are 100% emissions legal, the use of xTreme Deletes is recommended for track use only. Check local noise regulations for street legality. In addition to the xMOD variable sound and flow modules, this system incorporates MagnaFlow’s latest exhaust tuning advancement called No Drone Technology (NDT). MagnaFlow’s NDT, along with careful muffler design and placement, utilizes 1/4 wave passive noise cancellation to remove unwanted drone that can occur when creating a maximum performance, high flow exhaust system.
