4" High-Flow Downpipe Exhaust for 2020–2025 Ford F250 F350 F450 6.7L Powerstroke

Upgrade the exhaust flow of your 2020–2025 Ford 6.7L Powerstroke Diesel with this 4" high-flow downpipe. Designed as a replacement for the more restrictive factory downpipe, it provides a larger and smoother exhaust path to help reduce exhaust backpressure and improve overall exhaust flow. The improved airflow can help the turbocharger build boost more efficiently, improve throttle response, and reduce exhaust gas temperatures (EGT) during demanding driving conditions such as towing, hauling, climbing, and other high-load applications.

4" Downpipe Exhaust for 2020–2025 Ford 6.7L Powerstroke Key Features

• 4" High-Flow Design: The larger 4" diameter provides increased exhaust flow compared with the restrictive factory design, helping reduce exhaust resistance and backpressure.
• Improved Turbo Response: A smoother exhaust path allows exhaust gases to exit more efficiently, helping the turbocharger build boost more quickly and improving throttle response.
• Helps Reduce EGT: Improved exhaust flow can help manage exhaust gas temperatures under high-load conditions, making it especially suitable for towing, hauling, and extended climbs.
• Enhanced Power Potential: By improving exhaust flow and reducing restriction, the downpipe helps the engine and turbocharger operate more efficiently and provides a better foundation for additional performance upgrades.
• OE-Style Routing & Direct-Fit Design: Designed to follow the factory exhaust path for a straightforward installation without cutting or welding. Compatible with the factory turbocharger and many OE-routing exhaust configurations.
• Heavy-Duty Construction: Built to withstand high exhaust temperatures and demanding operating conditions while providing improved corrosion resistance and long-term durability.

Ideal for

• Daily driving and improved throttle response
• Towing trailers, RVs, and heavy loads
• Hauling and high-load applications
• Mountain driving and extended climbs
