Product Description

The Borla 140678 ATAK Cat-Back Exhaust System is engineered exclusively for 2015-2023 Dodge Challenger SRT-392 and Scat-Pack 392 models equipped with the 6.4-L HEMI V8 and cylinder-deactivation (MDS) technology. This aggressive ATAK system includes a merge X-pipe and valve simulators to override factory MDS valves and maintain consistent flow and sound without triggering warning lights.

Constructed from premium T-304 stainless steel with 2.75- mandrel bends and high-flow ATAK mufflers, the 140678 delivers Borla's signature high-volume tone while retaining bolt-on ease using OEM hangers. Exhaust tips reuse factory bezel/tip hardware - no cutting or modifications are required.

Made in the USA and backed by Borla's industry-leading One Million-Mile Limited Warranty, this system delivers uncompromised performance, bold exhaust note, and long-term reliability for Challenger owners who demand the most intense street sound without compromise.
