ATAK (Acoustically-Tuned Applied Kinetics) tuning calibrates the internal muffler cores for an uncompromising exterior note while keeping the cabin free of harsh resonance. It uses Borla's patented straight-through, multi-core design to increase exhaust velocity and free up power while producing the distinctive Borla Sound of Power. The system is built from premium T-304 austenitic stainless steel with ultra-smooth mandrel bends and CNC manufacturing for an accurate fit. Borla exhaust is handmade in the USA and backed by the Borla Million-Mile Warranty. It is 50-state emissions legal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSystem type: rear-section exhaust\u003c\/li\u003e\n\u003cli\u003eSound level: ATAK, Borla's most aggressive\u003c\/li\u003e\n\u003cli\u003eExit: dual split rear exit\u003c\/li\u003e\n\u003cli\u003eMaterial: T-304 austenitic stainless steel\u003c\/li\u003e\n\u003cli\u003eConstruction: patented straight-through multi-core, mandrel-bent, CNC manufactured\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003eEmissions: 50-state emissions legal\u003c\/li\u003e\n\u003cli\u003ePart number: 11831\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2013 Ford Mustang Shelby GT500\u003c\/li\u003e\n\u003cli\u003e2014 Ford Mustang Shelby GT500\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles does the Borla 11831 fit?\u003c\/h5\u003e\u003cp\u003eIt fits the 2013 and 2014 Ford Mustang Shelby GT500 with the supercharged 5.8L V8.\u003c\/p\u003e\u003ch5\u003eHow loud is the ATAK sound level?\u003c\/h5\u003e\u003cp\u003eATAK is Borla's most aggressive sound level.
