{"title":"ATS Diesel Exhaust Manifolds","description":"\u003cp\u003eThe factory exhaust manifold(s) on your Cummins, Duramax, or Powerstroke are built to flow a very particular amount of spent exhaust gases out of the engine and into the turbine housing of your turbo. Once you've increased the performance of your engine and its producing additional boost, the manifold(s) becomes a bottleneck in the system. Especially if you've swapped out your factory turbo to a larger unit and you haven't upgraded the manifold, you're really missing out! ATS Diesel Performance builds a variety of their Pulse Flow Exhaust Manifolds for numerous applications ranging in direct fitment and some even featuring larger T-4  flanges or offset and centered designs. Some manifolds feature a multi-piece design that allows the manifold to expand and contract which alleviates any cracking as the factory manifolds are known for, especially on Cummins applications. Other models feature a unique thicker, ductile iron design that does not require a multi-piece design to prevent against cracking. When you're ready for an upgrade, check out the ATS Pulse Flow Exhaust Manifolds!\u003c\/p\u003e","products":[{"product_id":"ats-pulse-exhaust-manifolds-01-10-gm","title":"ATS 2049004248 Pulse Flow Exhaust Manifolds 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.\u003cbr\u003e\u003cbr\u003eATS 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. \u003cbr\u003e\n\u003cbr\u003e\nWith 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.","brand":"ATS Diesel Performance","offers":[{"title":"Default Title","offer_id":52076850479469,"sku":"ATS-2049004248","price":1079.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/2487\/2301\/files\/10129.gif?v=1752689341"},{"product_id":"p-ats-pulse-flow-exhaust-manifold-kit-t4-03-07-ram-59l-common-rail-cummins","title":"ATS Pulse Flow 2 Piece Exhaust Manifold Kit (T4) 03-07 Ram 5.9L Cummins","description":"\u003cdiv\u003eGo with the flow by upgrading to the ATS Pulse Flow Exhaust Manifold for your Ram 5.9L Common Rail Cummins.
