• Ductile cast iron Y-pipe eliminates weld failures and provides smooth internal flow
• Fully divided Y-pipe design optimizes turbo spool time
• EGR compatible with included connector
• Flexible V-band connections for precise alignment and leak prevention
• Includes heavy-duty stainless steel up-pipe clamps
• Manufacturer Part Number: 1043917

Fits 2008-2010 Ford F-250 and F-350 Super Duty (6.4L).

Factory up-pipes on the 6.4L Power Stroke are prone to failure due to extreme heat cycling, which causes the bellows to crack. This leads to exhaust leaks, soot buildup, increased cabin noise, and sluggish turbocharger spool. The BD Diesel Up-Pipe Kit (1043909) is a durable, heavy-duty replacement designed to solve these common OE issues, making it an essential upgrade during turbocharger replacement or manifold repairs.

Engineered for longevity, these feed pipes are constructed from 304 stainless steel mandrel-bent tubing to ensure optimal flow and corrosion resistance. The expansion bellows are internally shielded to prevent the internal liner from collapsing or failing under pressure. This kit is fully EGR compatible, meeting emission requirements while providing a much more robust exhaust solution than the factory components.

• Constructed from mandrel-bent 304 stainless steel for superior durability
• Internally shielded expansion bellows prevent common heat-related failures
• Fully EGR compatible to maintain emissions compliance
• Improves turbocharger spool by eliminating exhaust leaks
• Manufacturer Part Number: 1043909

Includes: Exhaust manifold gaskets, EGR gasket, and turbocharger pipe gaskets.

Fits select 1999-2003 Ford F-250/F-350 Super Duty, Excursion, and E-350 Econoline (7.3L / 6.0L).

The BD Diesel Exhaust Up-Pipe Kit is engineered to replace the factory exhaust feed system, which is notorious for developing leaks that result in lost turbo drive pressure and increased Exhaust Gas Temperatures (EGTs). By utilizing 2-inch 304L stainless steel tubing, this kit maximizes the transfer of heat energy to the turbocharger while providing superior corrosion resistance compared to aluminized or 409 stainless steel. This kit requires the use of Ford 6.0L style exhaust manifolds for installation.

• 304L 2-inch stainless steel tubing prevents heat loss and resists burnout
• High-silicon ductile iron Y-adapter for thermal durability
• Internally shielded stainless steel expansion bellows for less restrictive flow
• Stainless steel gaskets replace factory crush donuts for a permanent, extended sealing life
• Prevents loss of turbo drive pressure to maintain performance
• Manufacturer Part Number: 1043900
• 12-month / 24,000-mile warranty

Fits 2008-2010 Ford F-250 and F-350 Super Duty (6.4L).

OE exhaust components on the 6.4L Powerstroke are prone to failure due to extreme heat cycling, leading to cracked manifolds and leaking up-pipe bellows. These failures cause exhaust leaks, soot buildup, and significantly slower turbo spool. The BD Diesel Up-Pipe and Manifold Kit is a heavy-duty solution designed to restore performance and provide long-term reliability.

The exhaust manifolds are engineered from 0.25-inch thick-walled Hi-Silicon ductile iron castings to resist cracking under high EGTs. Each port is gasket-matched to maximize flow, and the assemblies are finished in high-temperature black paint. The included up-pipes are constructed from mandrel-bent 304 stainless steel with a larger diameter to reduce restriction. These pipes feature internally shielded expansion bellows for superior durability compared to factory units.

• Material: 304 Stainless Steel (Up-Pipes) / Hi-Silicon Ductile Cast Iron (Manifolds)
• 0.25" thick-walled manifold casting for maximum heat resistance
• Internally shielded stainless steel expansion bellows
• Pre-drilled and tapped for pyrometer probes or pressure gauges
• Fully EGR compatible and meets emissions requirements
• Includes: Manifold gaskets, pipe gaskets, EGR gasket, turbo gaskets, and 6 exhaust studs
• Manufacturer Part Number: 1041484
