The ROUSH Active Exhaust Upgrade Kit converts a ROUSH Active-Ready exhaust into a full Active Exhaust for 2021–2023 Ford F-150 5.0L V8 applications. The kit includes an illuminated dash-mounted switch that toggles the system between open and closed modes, giving direct control over exhaust sound. This upgrade is explicitly compatible only with the Active-Ready ROUSH Performance exhaust Part #422264 and integrates with that system.
