ATS 2049004248 Pulse Flow Exhaust Manifolds for 01-04 GM 6.6L Duramax LB7

Description

Not only does the factory drivers side exhaust manifold have an unnecessary clearance depression that causes it to flow inconsistently with the passenger side, the manifolds themselves are prone to cracking and warping over time, possibly leaving you stranded.ATS Pulse Flow Exhaust Manifolds for the LB7 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 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.

About ATS Diesel Performance

ATS DIESEL PERFORMANCE

ATS Diesel Performance, based out of Arvada, Colorado, is a diesel performance manufacturing company that designs, engineers, and manufactures upgraded transmission components, valve bodies, patented heavy-duty torque converters, exhaust and intake manifolds, electronics, turbochargers, dual CP3 injection pumps, and more for Cummins, Powerstroke, and Duramax powered diesel trucks. Operating out of a humongous 110,000 square foot facility in the heart of the Rocky Mountains allows ATS to keep operations in-house, as opposed to overseas sourcing, and then grueling test their products at altitude and through grades and descents that would make other companies think twice. From full-time RV users who travel nonstop to high-horsepower competition-based vehicles, ATS has the answers.

ATS DIESEL TRANSMISSIONS

Clint Cannon and Ranee Elder founded Automotive Transmission Specialists in 1993. At that time, the company specialized in transmission repair for all types of vehicles. In 1997, the company "Performance Torque Converters" was founded, and they started doing torque converter rebuilds in-house. Bringing the capability of building torque converters in-house gave them more flexibility to service their racing customers. As the popularity of diesel trucks grew and more people became aware of the power upgrades available for their diesels, problems with diesel transmissions emerged.

Clint started research and development into a more robust torque converter to address the transmission issues. It was discovered that a clutch pack design was the answer to providing a robust torque converter. The development of the TripleLok Torque Converter and the company's focus on Diesel Performance products resulted in a rename of the company to ATS Diesel Performance.

By having their foot in the door before most, it allowed ATS Diesels transmission upgrades to grow with the demands of diesel trucks, putting them at the forefront of reliability. Fortunately for us, Clint didn't stop with transmissions and began to explore and refine upgraded turbochargers, intake and exhaust manifolds, and anything else to generate additional power with the ever-present mindset of maintaining powertrain reliability.
