Construction & Design

Every Borla ATAK Cat-Back Exhaust System is crafted from high-grade T-304 stainless steel, a material known for its exceptional durability and resistance to rust and corrosion. This premium steel outperforms lower-grade alternatives such as T-400 series alloys, ensuring the system maintains its structural integrity and appearance over time.

The system features mandrel-bent tubing, which preserves the diameter through bends to optimize exhaust flow and minimize restrictions. Borla’s use of computer numerical control (CNC) machining guarantees precise cuts and welds, resulting in a perfect fit that aligns seamlessly with factory mounting points and components.

Performance & Sound

The Borla ATAK system enhances engine performance by increasing exhaust velocity and reducing backpressure. The integrated merge X-Pipe improves exhaust scavenging, which helps the engine breathe more efficiently and can contribute to modest gains in horsepower and torque.

Acoustically, this system produces a deep, aggressive exhaust note that is louder and more pronounced than stock, yet refined enough to avoid drone during highway cruising. The signature BORLA Sound of Power provides an exhilarating auditory experience that complements the performance upgrades.

Installation & Fitment

The Borla ATAK Cat-Back Exhaust System is designed for a direct bolt-on installation on 2015–2023 Dodge Charger and 2015–2024 Chrysler 300 models with the 3.6L V6 engine. It utilizes factory mounting points and hardware, requiring no cutting or welding. While the system does not include exhaust tips, it is compatible with the vehicle’s factory bezel and valance, allowing you to reuse existing tips for a clean, factory-integrated appearance.

Installation can typically be completed with basic hand tools and moderate mechanical experience. Professional installation is recommended to ensure optimal fitment and performance.
