ATS Diesel 6.6L Duramax Pulse Flow Exhaust Manifolds

ATS Diesel 2001-2004 6.6L Duramax Race Performance Exhaust Manifolds.

ATS Pulse Flow Exhaust Manifolds for 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% increase in airflow. Not only will the Pulse Flow manifolds improve performance, they are a leap forward in 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 turbocharger. 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 they're still expanding as this will create more action on the turbine wheel & 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.

1941 Willys 6.6L Duramax BATMOBILE





Holy Cow Batman a Power Duramax Diesel.  This built diesel drag car is tearing up the track with is custom Batmobile look! The truck/car is a 1941 Willys with a 6.6L Duramax diesel engine under the hood and a full Batmobile body. Not only is this thing eye-catching to look at but it's running some blazing fast times on the track.  During the NHRDA spring nationals, they manage to run 177 MPH in the 1/4 mile!
