Product Description

The MBRP S5221304 resonator-back exhaust is engineered for the 3.5 L PowerBoost hybrid engine in the 2021-2024 Ford F-150. By employing full 3.00" mandrel-bent tubing and premium T304 stainless steel, this kit reduces flow restrictions and enhances exhaust tone and performance. The single-side exit layout preserves a sleek factory-style appearance while delivering an improved sound profile and tighter flow path.

Installation is designed to be straightforward - the system uses factory mounting points and hangers, making it suitable for experienced DIYers or professional installers alike. The "Street Profile" tuning provides a rich tone under throttle without being overly loud at cruise, making it a balanced upgrade for daily drivers and performance-minded owners. While fitment is confirmed for model years 2021 through 2024, always verify your truck's engine (3.5 L PowerBoost), exit configuration, and local emissions regulations before purchase.
