less restriction than stock manifolds and up-pipes. Channel areas were increased dramatically resulting in a 26 percent increase in airflow. Not only will the Pulse Flow manifolds improve performance, they are a leap forward on reliability. Cast out of High Silica Moly, these manifolds have the ability to run through more heat cycles (lifetimes worth) without fatigue, cracking, or warping.\u003C\/p\u003E\u003Cp\u003EWith each exhaust port inlet to the manifold, the main chamber continuously gets bigger, allowing for the added volume, but also to keep thermal velocity up as well. The expansion of the exhaust gasses through the manifold and up-pipe is what drives the turbine side of the turbo charger. The faster you can keep the velocity of the gas, the easier it is to spool the turbocharger.\u003C\/p\u003E\u003Cp\u003EThermal barriers play a part in this as well. Due to the material having a high ability to retain heat, the heat remains inside the manifold instead of being expelled. The hot exhaust gasses are still expanding as they exit the engine, and it is ideal to get those gasses into the turbocharger while theyre still expanding as this will create more action on the turbine wheel and result in a faster spool-up.\u003C\/p\u003E\u003Cp\u003EThis is one huge advantage to using a set of well-engineered exhaust manifolds over headers, which increase the time it takes the exhaust to reach the turbocharger due to the extra length added to the tubes in order to create equal-length pipes; the result of is the gasses are cooling and therefore contracting by the time they reach the turbine wheel, reducing the action created.\u003Cbr\u003E\u003Cstrong\u003EDetails:\u003C\/strong\u003E\u003C\/p\u003E\u003Cul\u003E\u003Cli\u003E6.6L Duramax Pulse Flow Exhaust Manifold Kit\u003C\/li\u003E\u003Cli\u003EBoth Driver and Passenger Sides\u003C\/li\u003E\u003Cli\u003EIncreased reliability\u003C\/li\u003E\u003Cli\u003EImproved exhaust flow\u003C\/li\u003E\u003Cli\u003EWon\u0027t crack like stock manifolds\u003C\/li\u003E\u003Cli\u003EIncludes everything you need for easy installation\u003C\/li\u003E\u003Cli\u003ECast Iron Manifolds\u003C\/li\u003E\u003Cli\u003EBlack Ceramic Coated Finish\u003C\/li\u003E\u003Cli\u003ESold As A Kit\u003C\/li\u003E\u003Cli\u003ESKU: 2049004248\u003C\/li\u003E\u003C\/ul\u003E\u003Cp\u003E\u003Cstrong\u003EFits Vehicles:\u003C\/strong\u003E\u003C\/p\u003E\u003Cul\u003E\u003Cli\u003E2001-2004 GM 2500|3500 Truck w\/6.6 Duramax Engine and No EGR Valve\u003C\/li\u003E\u003C\/ul\u003E\u003C\/div\u003E\n      \u003C\/article\u003E\n","dialogOptions":{"width":"80%","dialogClass":"product-quick-view","buttons":[],"modal":true,"title":"ATS Pulse Flow Exhaust Manifold Kit Fits 2001-2004 6.6L Duramax","classes":{"ui-dialog":"product-quick-view"}}}]
