Upgrade your 2015–2019 Ford 6.7L Powerstroke diesel with this high-performance 4" High-Flow Downpipe — designed for maximum flow, faster turbo spool, and increased boost potential. Crafted from premium 304 stainless steel, this 2-piece downpipe is a direct bolt-on replacement for your factory unit and fits seamlessly with both stock and aftermarket turbochargers.
Whether you're driving an F250, F350, F450, or F550, this downpipe improves exhaust gas evacuation from the turbine, reduces backpressure, and supports emissions-modified off-road builds (where legal).

❓ What does a downpipe do?
The downpipe on a turbocharged diesel engine routes exhaust gases from the turbo’s turbine housing into the exhaust system. A stock downpipe is often restrictive, reducing turbo efficiency and power output.
Replacing it with a 4" high-flow downpipe:
-
Reduces backpressure
-
Improves turbo spool time
-
Allows for more aggressive tuning
-
Increases horsepower and torque
-
Optimizes exhaust flow in tuned or deleted trucks
This upgrade is a must-have for diesel performance enthusiasts looking to remove bottlenecks in their exhaust system and push their Powerstroke to the next level.
