The Borla ATAK axle‑back for 2011–2012 Ford Mustang Shelby GT500 5.4L applies ATAK acoustical tuning to produce an aggressive exterior tone while keeping cabin resonance controlled. Made from premium T‑304 stainless steel with precision mandrel bends and chrome tips, the system increases flow for performance gains and pairs with Borla components to form a complete exhaust solution. It’s a vehicle‑specific, high‑flow rear upgrade.
