This results in quicker throttle response, lower exhaust gas temperatures (EGTs), and gains of up to 40 rear wheel horsepower. Whether you’re towing, daily driving, or building for performance, this upgrade helps your truck breathe easier under load.
Built from durable T409 stainless steel, this down pipe is made to handle heat, corrosion, and long-term use. The 2-piece design makes installation significantly easier, especially in the tight engine bay of the 6.4 Powerstroke.
This is a straightforward upgrade that delivers noticeable results in both performance and drivability.
Note: Not legal for sale or use in California.
