The Milltek Sport Valved Cat-Back Exhaust is designed for the Ford F-150 Raptor 3.5 V6 EcoBoost Gen 3 (2021+). Engineered with over 20 years of exhaust development experience, this system delivers the perfect balance of performance, sound, and style.
Over 20 years of exhaust expertise went into developing this system. A compact, purpose-built muffler improves flow and frees up space, while the dual-route center section increases flow efficiency and response when the valves are closed. This design keeps the closed-valve tone calm while improving throttle response, drivability, and overall system efficiency.
Constructed from high-quality T304L aircraft-grade stainless steel, the Milltek exhaust resists discoloration and corrosion while ensuring durability. Mandrel-bent piping maximizes exhaust flow without compromising mid-range torque, and the compact high-flow resonator refines the exhaust note for a sporty yet controlled sound.
