Product Description

The Borla 11978CB ATAK Axle-Back Exhaust System delivers Borla's most aggressive exhaust tone for the 2021-2025 Ford Bronco equipped with the 2.7L V6 EcoBoost engine. Engineered specifically for the Bronco platform, this axle-back system provides a more exciting driving experience with the distinctive Borla "Sound of Power" without any annoying interior drone. The entire assembly is constructed from premium T-304 stainless steel with a black ceramic high-temperature coating for superior durability and a stealthy appearance. A 2.5" inlet flows into a 2.75" muffler inlet pipe and exits through dual 2.5" tailpipes fitted with 4" round black coated stainless steel tips. Ultra-smooth mandrel bends ensure maximum exhaust flow and power gains, while precision CNC manufacturing guarantees an accurate factory-quality fit. Borla's custom muffler hanger design moves the hanger out of sight for a clean, finished appearance. Direct bolt-on installation uses factory mounting locations with no cutting, welding, or modifications required. Made in the USA and backed by Borla's industry-leading Million-Mile Warranty for street-legal applications.
