The ATS Pulse Flow Exhaust Manifold is a direct replacement for the factory manifold features on the 2003-2007 5.9L Cummins but is built to outflow and outlast the factory unit in every way. Designed as a two piece unit to allow for expansion and contraction, rather than cracking, and also features a larger inside diameter for quicker heat expulsion. The 2 piece design allows for better thermal expansion and contraction so the chance of cracks and warping is greatly reduced. Multiple pieces also makes installation and any future replacements easier.
ATS Pulse Flow Exhaust Manifolds for your Dodge Cummins feature a multi-piece pulse flow design, patented ball flange design, high-temperature coated, and tapped for a pyrometer probe. Your turbocharger will spool up sooner, will have less exhaust back pressure and you'll never have shrinking, breaking, cracking and gasket problems.
This manifold is for the T3 turbo which most stock versions are, if you have a T4 flanged turbo this will not fit for proper application. If you are unsure, please check before ordering.
