ATS Exhaust Manifolds increase velocity of airflow to the turbo reducing lag!

High flow exhaust manifolds reduce the back-pressure and help drive your turbo!

ATS Pulse Flow Exhaust Manifolds give you 30% over stock air flow with no restriction

ATS Pulse Flow Exhaust Manifolds for the 2001 to 2005 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 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 & 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.

ATS RETURN POLICY: ATS requires a 25% restocking fee on any returned item. This is something at Thoroughbred Diesel we have no control over but ATS enforces everyone to charge a 25% restocking fee on any return and we like to be up front with our customers.
