Stop
exhaust manifold cracks in their tracks with BD’s new Pulse
exhaust manifold for the Dodge-Cummins. Cast from high silicon ductile
iron, the Pulse features expansion joints that allow the manifold
to expand and contract without cracking or exhaust leaks. As the name
would imply, these manifolds are “pulse tuned” to assist
in combustion chamber evacuation and increased exhaust flow.
The result is
quicker turbo spool-up, reduced backpressure, increased power and
better fuel economy. Some kits include stainless steel fasteners
and washers to prevent lost or loose manifold bolts - gaskets are
available separately.

The
three piece pulse manifold for the Dodge Cummins application, with
its pulse exhaust flow design, increases exhaust gas efficiency, helping
to spool up the turbocharger sooner with less exhaust back-pressure.
The pulse manifold design eliminates the problems that persist with
the stock manifold in both 12 and 24 valve engines - the shrinking
and breaking of the manifolds. The stock manifolds can shrink as much
as 3/8”. This can cause manifold-cracking, gasket problems,
and exhaust flow problems created by exhaust port misalignment. In
12 valve engines, one sees sheared off manifold bolts, and this extreme
shrinkage can sometimes break the ears off the head where the stock
manifold is attached. The three-piece pulse manifold is cast of a
much higher-grade material than the stock manifold, which will handle
far more heat without being brittle. This three-piece pulse manifold
comes with new socket head cap screws and washer.
