    Aggressively Thunderous Racing Sound. The Borla ATAK Cat-Back Exhaust produces incomparably aggressive racing exhaust notes, allowing the Challenger to dominate any road. This remarkable racing growl is a product of Borla's Acoustically-Tuned Applied Kinetics (ATAK) technology that creates the highest legal decibel levels of exhaust sound – the most aggressive series in Borla's exhaust lineup.

    Maximum Power Boost. This Borla ATAK Exhaust features straight-through, multi-core engineering that delivers maximum exhaust velocity for an exceptional power boost and improved torque. This exhaust system effectively reinforces the Challenger engine's capabilities. In addition, the high-flow X-pipe facilitates a more efficient flow for maximum exhaust performance.

    Premium Construction. This ATAK Cat-Back Exhaust is constructed from T-304 austenitic stainless steel of premium durability. Austenitic grades are particularly highly resistant to corrosion and high temperatures. Furthermore, the solid walls and full-weld assembly reinforce the pipe and add strength to resist mechanical failure.

    Quick Installation. This ATAK Exhaust features a direct bolt-on installation that requires moderate mechanical skills. This upgrade is conveniently designed for OEM exhaust hangers and mounts. The installation process takes approximately 2 hours.

    Active Exhaust Valves or Valve Simulators. This Borla Exhaust System is available with either replacement Active Exhaust Valves or Valve Simulators. The replacement Borla Active Exhaust Valves replace the OEM valves and plugs directly into the factory harness to operate just like stock. The Valve Simulator option does not include valves, so the exhaust is always open and at its loudest. The included "valve simulators" plug into the factory harness to trick the system to think the valves are still in place, therefore avoiding a check engine light.

    Non Active Exhaust.

    Application. This Borla ATAK Cat-Back Exhaust is designed for 2015-2020 Dodge Challenger 5.7L HEMI models with or without Active Exhaust Valves. Please select your application from the options available.
