Construction & Design

The Borla ATAK Cat-Back Exhaust is crafted from high-grade T-304 austenitic stainless steel, known for its exceptional resistance to corrosion and heat. This material choice ensures longevity and maintains a polished appearance even under extreme conditions. The exhaust piping is mandrel-bent to maintain consistent diameter throughout bends, preventing flow restrictions and maximizing performance gains.

The system features a Merge X-Pipe, which improves exhaust scavenging by merging exhaust pulses smoothly, resulting in better engine breathing and increased power output. Dual polished rectangular tips with an angle-cut design provide a distinctive, aggressive rear-end aesthetic that complements the Dodge Challenger’s muscular styling.

This aggressive tone matches the raw power of the 6.4L HEMI engine, delivering an exhilarating auditory experience during acceleration and cruising. The free-flowing design and Merge X-Pipe contribute to improved horsepower and torque by reducing backpressure and enhancing exhaust gas evacuation.
