Are you needing to replace the exhaust manifolds, up pipes and up pipes. While most get one and forget the other, almost all forget to get new hardware. This exhaust manifold kit includes. 

• BD Diesel Heavy duty Exhaust manifolds
• BD Diesel up pipes
• BD Diesel Exhaust manifold hardware kit

Heavy walled manifolds hold in exhaust gas temperatures to enhance turbine pumping efficiency. The runners have been ported to improve velocity and evacuate the cylinders. Manifolds are coated to resist corrosion and are pre-drilled for pyrometer probes. These units replace the old rusted and leaking stock exhaust manifolds that normally require extensive cleaning and machine work to be recovered from warping and distortion. The manifold set comes with both passenger & driver's side units and feed pipe mounting hardware. With the stock manifolds considered a maintenance item due to corrosion and leaking, this set is an excellent preventative replacement item whenever doing other engine work.

• Heavy walled manifolds hold in exhaust gas temperatures to enhance turbine pumping efficiency
• Optimized runners to improve velocity and evacuate the cylinders
• Coated to resist corrosion
• Pre-drilled for pyrometer probes
• Replaces old rusted and leaking stock exhaust manifolds that normally require extensive cleaning and machine work to be recovered from warping and distortion

Replaces the factory exhaust up-pipes (exhaust manifold to the turbo) which are prone to leakage due to deterioration. BD up-pipes are designed to minimize restriction to the turbo utilizing internally shielded expansion bellows. The turbo Y-adapter is made from high-silicon ductile iron. The BD up-pipes are a durable, longer-life replacement for this common PowerStroke problem and are perfect as an upgrade while performing other engine or transmission repairs.

• Fully EGR compatible - Meets emission requirements
• Ductile cast iron Y-pipe design is a perfect fit and eliminates leaks and weld failures
• Larger diameter 304 stainless steel Up-Pipes includes internally shielded stainless steel expansion bellows
• V-band connections provide a flexible, easy aligning tight fit
• Stainless steel up-pipe clamps included
• Maximizes your turbo response time and eliminates exhaust leaks
• Fully divided Y-pipe optimizes turbo spool
• Smoother internal Y-pipe geometry than competitors up-pipe designs

Typical aftermarket exhaust manifold bolts are much shorter than stock which after numerous heat cycles can cause them to fatigue and start to stretch, leading to exhaust leaks and possible breakage after repeated re-torques. The finish and coating on most of these bolts can also lead to premature corrosion and zinc embrittlement. Replace damaged or corroded exhaust manifold bolts with BD's class 10.9 bolts and spacers which improve thermal durability to stand up to the heat and non-Zinc plated fasteners prevent zinc embrittlement.

• Exhaust spacers ensure fastener operates in elastic stretch without fracture or permanent yield
• Class 10.9 Hardware
• Non-Zinc-plated fasteners prevent zinc embrittlement
• Qty 16 exhaust spacers (18mm)
• Qty 16 flange head exhaust bolts (M8x1.25 – 40mm 10.9)
