The Borla ATAK axle-back exhaust system is a 2.5 inch diameter design built for the 2024-2025 Ford Mustang GT 5.0L V8 that is not equipped with Active Exhaust. Its muffler uses Polyphonic Harmonizer technology, with patented internal units of different pipe diameters and lengths that create multiple exhaust notes harmonizing into a clean, rich, full-bodied sound. It delivers the aggressive ATAK sound level with no drone inside the vehicle and finishes with 4 inch bright chrome T-304 stainless steel tips. The system fits both coupe and convertible models. Borla uses straight-through, patented multi-core technology with ultra-smooth mandrel bends and CNC manufacturing for increased exhaust velocity, added power, and an accurate bolt-on fit. Built from premium T-304 stainless steel, superior to T-400 series materials such as 409, this axle-back mounts behind the factory catalytic converters and is 50-state emissions legal. Every Borla exhaust is handmade in the USA and backed by the Borla Million-Mile Warranty.
