ATS 204-900-4248 PULSE FLOW EXHAUST MANIFOLD KIT FOR 01-04 GM 2500HD/3500HD WITH 6.6L DURAMAX

ATS Pulse Flow Exhaust Manifolds for the 2001 to 2004 6.6L Duramax offer far 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.

With 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.

Thermal 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.

This 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.

The ATS 204-900-4248 Pulse Flow Exhaust Manifold Kit for 2001-2004 Duramax 6.6L LB7 engines is a superior aftermarket upgrade designed to enhance the performance and reliability of your vehicle. Engineered to provide less restriction than stock manifolds and up-pipes, these Pulse Flow Exhaust Manifolds offer a significant 26 percent increase in airflow, resulting in improved overall engine efficiency.

Crafted from High Silica Moly, these manifolds are built to withstand numerous heat cycles without succumbing to fatigue, cracking, or warping. The unique design features expanded channel areas and larger main chambers, ensuring optimal thermal velocity and improved spooling of the turbocharger. By retaining heat within the manifold and facilitating faster exhaust gas expansion, these manifolds contribute to quicker turbocharger response and increased performance.

Compared to traditional headers, the ATS Pulse Flow Exhaust Manifolds provide a more direct path for exhaust gases, reducing cooling and contraction before reaching the turbocharger. This results in enhanced turbine wheel action and faster spool-up times, making it a preferred choice for enthusiasts seeking both reliability and performance gains.

The ATS 204-900-4248 kit includes components for both driver and passenger sides, featuring cast iron manifolds with a durable black ceramic-coated finish. With easy installation and compatibility with 2001-2004 GM 2500|3500 trucks equipped with the 6.6 Duramax engine and no EGR valve, this kit is an excellent choice for diesel enthusiasts looking to unlock the full potential of their vehicles.

Take your Duramax engine to the next level with the ATS Pulse Flow Exhaust Manifold Kit, a reliable and high-performance upgrade that delivers on both power and durability.
