Description

Improve exhaust flow and turbo performance with the MBRP FS9CA459 4″ Turbo Down Pipe for the 2011–2015 6.7L Powerstroke. Designed to replace the restrictive factory down pipe, this upgrade allows your turbo to breathe more efficiently right out of the exhaust housing.

Constructed from durable T409 stainless steel, this down pipe is built to handle high temperatures while offering solid corrosion resistance for long-term reliability. The full 4-inch diameter significantly reduces backpressure, helping deliver faster turbo spool, improved throttle response, and lower exhaust gas temperatures under load.

As part of MBRP’s Armor Plus Series, this system strikes a strong balance between performance and durability. It is engineered as a direct-fit upgrade for Ford diesel trucks, ensuring proper fitment and a straightforward installation process.

This is a diesel-only component and is not for sale in California.
