Product Description

The MBRP FS9CA460 is a high-flow turbo down-pipe engineered specifically for the 6.7 L PowerStroke diesel engine in 2015-2016 Ford Super Duty trucks. Its full 4" diameter mandrel-bent design, constructed from premium T-409 stainless steel, enables improved exhaust flow and reduced back-pressure - providing better turbo performance and lower exhaust gas temperatures, which is critical for heavy towing or performance applications.

Installation is straightforward thanks to its direct-fit design for the vehicle platform listed. This down-pipe is optimized for performance builds - whether you're upgrading turbos, installing a full high-flow exhaust system, or building a rugged heavy-duty rig. While fitment for 2015-2016 is confirmed, compatibility for other years or variants may require additional verification. Always confirm your engine and turbo outlet before purchase, and check local emissions regulations to ensure compliance.
