Take your 2024-2026 Ford Mustang GT to the next level with the Borla 140963 ATAK Cat-Back Exhaust System. Designed specifically for Mustang GT coupe models equipped with Active Exhaust, this premium True Dual exhaust system delivers Borla’s most aggressive ATAK sound profile while maintaining a drone-free driving experience.
The Borla 140963 features a full 3" diameter True Dual design with an integrated Merge X-Pipe that improves exhaust scavenging, enhances exhaust flow, and delivers a deeper, more aggressive exhaust tone. The system retains full factory Active Exhaust functionality through integrated active valves, allowing you to maintain OEM drive mode sound control while dramatically upgrading sound and performance.
The mufflers incorporate Borla’s advanced Polyphonic Harmonizer Technology, utilizing patented internal pipe configurations of varying diameters and lengths to create multiple harmonized exhaust notes for a clean, rich, full-bodied sound unique to the Mustang GT platform.
Constructed from premium mandrel-bent T-304 stainless steel, this Cat-Back system offers exceptional corrosion resistance, durability, and long-term performance. The system is finished with aggressive 4" round bright chrome T-304 stainless steel exhaust tips that perfectly complement the styling of the S650 Mustang GT.
This system includes two 3" O.D. x 2.25" O.D. x 7" long adapters for clamp-on installation to the factory exhaust system. Do not use the included adapters for vehicles equipped with full 3" inlets. Precision CNC manufacturing ensures an accurate bolt-on fit and straightforward installation.
Borla’s patented straight-through and multi-core technology improves exhaust velocity to help unlock hidden horsepower, sharpen throttle response, and deliver the unmistakable BORLA® Sound of Power.
