CVF Catted Down-Pipes EcoBoost F-150 2017-2020

CVF Stainless Steel Catted Down-Pipes with Turbo Exhaust Adapters — 2017–2020 3.5L EcoBoost F-150

These CVF Stainless Steel Catted Down-Pipes deliver improved exhaust flow for your turbocharged 3.5L EcoBoost F-150, engineered specifically for 2017–2020 3.5L EcoBoost F-150 trucks. Built from durable stainless steel and including dedicated turbo exhaust adapters, this down-pipe system is designed to replace the factory down-pipes with a less restrictive, higher-flowing alternative while retaining catalytic converters for emissions compliance.

Improved Exhaust Flow from the Turbos

The down-pipes are among the most restrictive sections of a turbocharged engine’s exhaust system, sitting directly after the turbochargers. Replacing the factory down-pipes with a less restrictive design can help improve exhaust gas flow away from the turbos, which may contribute to improved turbo spool characteristics and overall exhaust efficiency compared to the factory configuration.

Stainless Steel Construction for Durability

Built from stainless steel, these down-pipes are engineered to resist corrosion and withstand the high exhaust gas temperatures generated by a turbocharged engine, offering improved long-term durability compared to standard mild-steel exhaust components.

Catted Design for Emissions Compliance

Unlike a “catless” down-pipe design, these down-pipes retain catalytic converters, helping maintain emissions system function and compliance in regions with emissions testing requirements. This makes them a practical choice for EcoBoost owners who want improved exhaust flow without eliminating catalytic converter functionality.

Included Turbo Exhaust Adapters

This kit includes dedicated turbo exhaust adapters, engineered to ensure a proper, sealed connection between the turbochargers and the new down-pipes. This helps ensure correct fitment and reduces the risk of exhaust leaks at this critical connection point.

Purpose-Built Fitment for the 3.5L EcoBoost F-150

This down-pipe system is specifically engineered for the 2017–2020 3.5L EcoBoost F-150 platform, ensuring correct fitment with the factory twin-turbo configuration used on this generation of EcoBoost engine. Always confirm your exact engine and trim configuration before ordering.

Who Is This Product For?

The CVF Stainless Steel Catted Down-Pipes are ideal for:

• 2017–2020 3.5L EcoBoost F-150 owners wanting improved exhaust flow
• Drivers wanting to retain catalytic converters for emissions compliance
• Those upgrading their turbocharged engine’s exhaust efficiency
• Truck owners building a broader EcoBoost performance package
• Owners wanting a durable, stainless steel down-pipe upgrade

Why Choose Catted Down-Pipes?

For EcoBoost owners who want improved exhaust flow without sacrificing emissions compliance, a catted down-pipe design offers a practical middle ground — better flow than the factory down-pipes, while retaining catalytic converters required in many regions for passing emissions inspections.

Important Installation and Compliance Considerations

Aftermarket exhaust modifications, including down-pipes, may be subject to regional emissions regulations. Even with catalytic converters retained, always confirm compliance with your local emissions laws before installation. Professional installation is recommended given the complexity of removing and replacing turbo-connected exhaust components.

Installation & Fitment Notes

This down-pipe kit is designed specifically for 2017–2020 3.5L EcoBoost F-150 trucks. Always confirm your exact engine and configuration before ordering. Professional installation is recommended to ensure proper sealing at the turbo adapter connections and overall exhaust system integrity.
