Construction & Design

The system is constructed from premium T-304 stainless steel, which offers superior corrosion resistance and durability compared to lower-grade materials like T-400 series steel. This high-quality metal ensures the exhaust system withstands harsh conditions and maintains its finish over time.

Every pipe and component is mandrel-bent to maintain consistent diameter throughout the bends, minimizing flow restrictions and maximizing power gains. The mirror-polished stainless steel tips not only enhance aesthetics but also resist discoloration from heat and road elements.

Manufacturing precision is achieved through computer numerical control (CNC) machining, ensuring each part fits perfectly with factory mounting points and requires no modifications.

Performance & Sound

The Borla ATAK Cat-Back system is designed to unlock hidden horsepower by increasing exhaust velocity and reducing backpressure. The merge X-Pipe improves scavenging, which enhances engine efficiency and throttle response.

The signature ATAK® sound is aggressive and commanding, delivering a deep, throaty exhaust note that intensifies under acceleration. This distinctive sound profile is favored by performance enthusiasts who want their Challenger to stand out audibly without drone during cruising.

Additionally, the improved exhaust flow can contribute to better fuel economy and overall driving excitement.
