      Aggressively Thunderous Racing Sound. The Borla ATAK Cat-Back Exhaust produces incomparably aggressive racing exhaust notes, allowing the MDS equipped 5.7L 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.

      Application. This Borla ATAK Cat-Back Exhaust fits 2016-2020 Dodge Challenger 5.7L models that is equipped with MDS (Cylinder Deactivation) Valves.

        sounds great, really nice quality

        Before this one I have the Flowmaster outlaw catback for my 2017 challenger, with valve, and after couple month flwmaster on turned my CEL on, cuz the valve got stuck and when I trying to get the warranty claimed from the website, they never respond. Then I have to change the catback to pass the inspection, this one compare to flowmaster have lot different, first thing is its much quiet in the car, no more drones, and outside sound effect will remain same plus u will never need to worry about the CEL LOL.

      Does this system come with exhaust tips? In the image it looks like you're supposed to re-use the stock exhaust tips, but mine are welded on from the factory
