The ATS two 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.

This pulse manifold design eliminates the problems that persist with the stock manifold in ISBe engines, that is namely the shrinking and breaking of the manifolds. The stock manifold in ISBe engines can shrink as much as 3/8 of an inch. This causes exhaust gasket problems, manifold-cracking problems, and exhaust flow problems created by exhaust port misalignment.

Expansion and contraction of the ATS pulse manifold is taken up in the  expansion joint. The expansion joints is unique in design. Advanced Turbo Systems holds a U.S. patent in the expansion joints design and function.  One set of bolt holes have merely a clearance fit where the manifold attaches to the cylinder head, the other set of bolt holes have more clearance for expansion. The end castings are where the function of this design becomes unique. The end castings that install into the straight bore of the center casting are a ball circumference seal arrangement. This allows the expansion joint to have interference fit and still assemble the manifold easily; while creating an excellent seal arrangement which allows for expansion and contraction of the manifold while maintaining a positive seal. The end castings of this manifold have one hole that is bolt clearance only. This insures near perfect exhaust port alignment without exhaust manifold movement on the head. This eliminates gasket and bolt loosening problems.

The ATS two piece pulse manifold is cast of a much higher-grade material than the stock manifold. Instead of being just cast iron like the stock manifold, the ATS manifold is a ductile casting, which will handle far more heat without being brittle. This pulse manifold is a high molly-silicon-ductile casting that is machined on state of the art palletized CNC machining centers. All Manifolds come Pre-Assembled with Black High Temperature Coating and Pre-Tapped for Pyrometer Probe.
