This hydroformed Borla SwitchFire X-pipe is designed to replace the Merge X-pipe in Borla 3 inch Cat-Back systems for the 2018-2025 Ford Mustang GT and 2024-2025 Ford Mustang Dark Horse, and it is designed to work with those Borla Cat-Back systems only. Hydroforming gives the center section a lower profile than a conventional SwitchFire X-pipe. The pipe measures 21.1 inches long by 7.8 inches wide by 5 inches high, with a 2.75 inch outside-diameter inlet and a 3 inch inside-diameter outlet. By eliminating the turbulent center intersection of a standard X-pipe, Borla's patented SwitchFire design blends the combustion pulses from both sides of the engine for improved performance, producing an aggressive custom sound and added power. Clamps are not included; reuse the clamps from the Borla Merge X-pipe in the Cat-Back system. It is built from premium T-304 austenitic stainless steel, superior to T-400 series materials such as 409, for lasting performance and durability. Ultra-smooth mandrel bends support maximum flow and power, and precision CNC manufacturing ensures an accurate fit. Like all Borla exhaust, it is handmade in the USA and backed by the Borla Million-Mile Warranty.
