The aggressive ATAK sound level provides a more exciting drive without any drone. The entire assembly is coated black with a high-temperature finish. The system uses a 2.5in inlet that flows into a 2.75in pipe and exits through dual 2.5in tail pipes with a single 4in round black coated T-304 stainless steel tip on each tail pipe. A custom muffler hanger design tucks the hanger out of sight for a clean appearance. T-304 stainless steel construction adds durability over the stock exhaust, while ultra-smooth mandrel bends and precision CNC manufacturing ensure maximum flow and an accurate fit. This axle-back installs behind the factory catalytic converter and retains all factory emissions equipment. It is made in the USA and backed by Borla's Million-Mile Warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSystem type: Axle-Back exhaust system\u003c\/li\u003e\n\u003cli\u003eSound level: ATAK (aggressive)\u003c\/li\u003e\n\u003cli\u003eMaterial: T-304 stainless steel\u003c\/li\u003e\n\u003cli\u003eSystem layout: 2.5in inlet into 2.75in pipe, dual 2.5in tail pipes\u003c\/li\u003e\n\u003cli\u003eTips: single 4in round black coated T-304 stainless, one per tail pipe\u003c\/li\u003e\n\u003cli\u003eFinish: high-temperature black coating over the entire assembly\u003c\/li\u003e\n\u003cli\u003eHidden muffler hanger design\u003c\/li\u003e\n\u003cli\u003eConstruction: mandrel-bent, CNC-manufactured, direct bolt-on\u003c\/li\u003e\n\u003cli\u003eNo-drone design\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003eWarranty: Borla Million-Mile Warranty\u003c\/li\u003e\n\u003cli\u003ePart number: 11978CB\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2021 Ford Bronco\u003c\/li\u003e\n\u003cli\u003e2022 Ford Bronco\u003c\/li\u003e\n\u003cli\u003e2023 Ford Bronco\u003c\/li\u003e\n\u003cli\u003e2024 Ford Bronco\u003c\/li\u003e\n\u003cli\u003e2025 Ford Bronco\u003c\/li\u003e\n\u003cli\u003e2026 Ford Bronco\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat does the Borla 11978CB fit?\u003c\/h5\u003e\u003cp\u003eIt fits 2021-2026 Ford Bronco models with the 2.7L V6 engine and 4WD.
