Roush 2021+ Ford F-150 Active-Ready Cat-Back Exhaust - 422264

The Roush Active-Ready Cat-Back Exhaust System (Part #422264) is a purpose-built performance exhaust upgrade engineered specifically for the 2021–2026 Ford F-150 equipped with the 5.0L V8 engine. Designed by Roush Performance — one of the most recognized names in Ford-focused performance engineering — this cat-back system delivers increased exhaust flow and an aggressive Roush exhaust note that transforms the soundtrack of your F-150. What sets this kit apart from a standard cat-back is its intelligent "Active-Ready" design: it lays the groundwork for a full active exhaust upgrade down the road, giving you flexibility that most aftermarket systems simply don't offer.

Key Features & Benefits

• Active-Ready Architecture: The system is designed to be upgraded with Roush Part #422265, which converts it into a full active exhaust system with selectable loud and quiet modes — a rare and valuable feature for buyers who want daily-driver comfort without sacrificing weekend performance capability.
• Increased Exhaust Airflow: The Roush cat-back design improves exhaust flow over the factory system, which can contribute to a more responsive throttle feel and a more liberated engine character on your 5.0L V8.
• Aggressive Roush Sound: Purpose-tuned for the F-150's 5.0L V8, this exhaust delivers the deep, muscular exhaust note Roush is known for — without the drone or harshness of poorly engineered generic systems.
• Direct-Fit Design: Engineered specifically for the 2021–2026 F-150 platform with 141"–163" wheelbase, this is a vehicle-specific fit — not a universal system — meaning straightforward installation using existing mounting points.
• Upgrade Path Built In: Rather than replacing the entire system later, the Active-Ready designation means your investment today is protected — add the active valve controller kit (sold separately as #422265) when you're ready for on-demand volume control.
• Roush Performance Engineering: Developed by a brand with decades of Ford-specific performance expertise, this exhaust is tuned and validated for the 14th-gen F-150 5.0L application.

Frequently Asked Questions

Q: What years and engines does the Roush 422264 fit?
A: This exhaust is designed for the 2021–2026 Ford F-150 equipped with the 5.0L V8 engine and a wheelbase of 141" to 163". It is not designed for EcoBoost or other engine variants.

Q: What does "Active-Ready" mean — does this exhaust already have active valve functionality?
A: "Active-Ready" means the cat-back system is engineered and pre-configured to accept the Roush active exhaust upgrade kit (Part #422265), which is sold separately. In its base form (422264 only), the system does not include the active valve controller or selectable loud/quiet modes. Adding Part #422265 later converts it into a full Roush Active Exhaust system with on-demand volume control.

Q: Can I add the active exhaust functionality later, or do I need to buy everything at once?
A: You can absolutely add it later. That's the purpose of the Active-Ready design. Installing Part #422264 now and adding Part #422265 at a future date is a supported and intentional upgrade path from Roush.

Q: How do I confirm this system fits my specific F-150 configuration?
A: The key fitment factors are the model year (2021–2026), engine (5.0L V8), and wheelbase (141"–163"). If you're uncertain about your wheelbase — especially on extended or crew cab long-bed configurations — contact our team with your VIN and we'll verify fitment before your order ships.
