This premium direct bolt-on upgrade addresses the notorious cracking and warping issues of the factory cast iron manifold while providing superior exhaust flow, faster turbo spool-up, reduced back pressure, and dramatically lower exhaust gas temperatures (EGTs) — especially beneficial for towing and heavy loads.\r\nUnlike single-piece stainless steel designs that can stress gaskets, bolts, and even the cylinder head due to excessive expansion, the innovative 2-piece construction with built-in expansion joints allows controlled thermal movement for maximum durability and reliability. CFD (Computational Fluid Dynamics) tested and optimized, this manifold flows over 23% better than stock, balancing exhaust pulses for quicker response and more even cylinder temperatures.\r\nCast from high-nickel ductile iron (similar to turbine housing material) for exceptional heat resistance, this manifold is the top choice for 3rd Gen Cummins owners seeking proven performance without compromises.","brand":"Diesel Power Source","offers":[{"title":"Default Title","offer_id":52700002451743,"sku":"MAN0161 GAS0131","price":624.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0813\/2195\/1519\/files\/MAN0161GAS0131-1.png?v=1784746504","url":"https:\/\/massdepot.com\/products\/diesel-power-source-2-piece-t3-exhaust-manifold-2003-2007-dodge-ram-5-9l-cummins-high-flow-performance-lower-egts-direct-bolt-on-oem-5135788ab-5135788ac-4931224","provider":"Mass Depot","version":"1.0","type":"link"}
