Product Description

The Borla 11975CB is an ATAK axle-back exhaust system designed specifically for the 2021-2026 Ford Bronco equipped with the 2.3L EcoBoost turbocharged four-cylinder engine. The ATAK sound level is Borla's most aggressive exhaust tone, delivering a deep, throaty growl under acceleration while engineered to eliminate interior drone at highway cruise speeds. This axle-back system replaces the factory mufflers, rear piping, and exhaust tips while retaining the factory catalytic converters and mid-pipe. The entire assembly is finished in a black high-temperature coating for a stealthy, trail-ready appearance, and exits through dual 2.5" tailpipes fitted with 4" round black coated T-304 stainless steel rolled-edge angle-cut tips. Borla's custom muffler hanger design repositions the hanger out of sight for a clean undercarriage look. All piping is CNC mandrel-bent from T-304 stainless steel for maximum exhaust flow and precision fitment. Installation is a direct bolt-on process requiring no welding, drilling, or permanent modifications -- estimated install time is 1 to 3 hours with basic hand tools and a vehicle lift. This system fits both 2-door and 4-door Bronco models with automatic or manual transmission. Made in the USA and backed by Borla's Million-Mile warranty on stainless steel construction, with a 1-year warranty on black coatings and tip finishes.
