A resonator-back exhaust built specifically for the 2021-2026 PowerBoost hybrid F-150, single side exit, tuned for MBRP's Street sound profile.

why this one — MBRP sells this as its own PowerBoost-specific listing rather than a shared EcoBoost part, and a resonator-back keeps more of the factory piping than a full cat-back for a milder upgrade.
