Exhaust Manifold - Pulse - Ductile Iron - Dodge Cummins - Each

BD Diesel Cast Exhaust Manifold - Dodge 6.7L 2008-2012

Fully divided pulse manifold made from high-silicon ductile iron and designed to withstand extreme temperatures and vibration. Precision slip joints allow the manifold to expand and contract, which reduces cyclic thermal fatigue and greatly increases manifold longevity.

Product Overview

Aftermarket exhaust manifolds that increase the internal bore size of their units compared to the port size on the cylinder head cools the exhaust inside the manifold only, but, the temperatures inside the combustion chamber is higher because of less turbo boost.

This has a negative effect on engine performance as it decreases turbo drive pressure energy and falsely lowers EGT readings. EGT is normally monitored by the driver to determine cylinder temperatures and by changing the base temperature referred to can result in engine damage.

BD's Full Bore exhaust manifold restores exhaust flow balance, improves power and reduces EGT's inside the combustion chamber. All of which is accomplished by maintaining internal bore size thus maintaining turbo drive pressure. Get better performance and save hundreds of dollars by using BD product versus other aftermarket manifold kits.

Made from high-silicon ductile iron, the Full Bore is a direct, bolt-in replacement for the factory manifold and is even drilled and tapped to accept the most popular EGT probes.

Note for Australian and European Markets

Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components, pedals, shifters, linkages, wing mirrors, instrument clusters, panhard rods/traction bars, drag links, brake boosters, brake or clutch lines, accelerator cables, heater cores, some master cylinders and adjacent parts can vary between LHD and RHD configurations. In some models compenents such as windscreen wiper arms, motors and linkages could differ in their size and orientation. Items such as floor mats & dash mats may have differences in their structure around the front row (or padding in different locations). In many cases items are identical depending on the design of the vehicle and part, but may have differing mounts, lengths or bolt patterns. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations.
