AFE 46-40024 BladeRunner Exhaust Manifolds 30793 26.00 AFE 46-40024 BladeRunner Exhaust Manifolds
$ 517.75
The AFE 46-40024 BladeRunner Exhaust Manifolds feature a bolt-on design and will increase power, performance, and exhaust flow in your 2001-2016 GM 6.6L Duramax. Machined Ports: These manifolds have both the inlet and the outlet ports machined to match the factory gaskets. This allows for maximum flow, without compromising gasket performance. Auxiliary Ports: An Exhaust Gas Temperature (EGT) probe port is incorporated into each manifold for easy installation of gauges or testing equipment. There are three additional cast in bosses provided to allow for alternate testing points. Hassle-Free Installation: These manifolds are compatible with the stock up-pipes, which allows the manifolds to be installed without having to remove the turbocharger down-pipe or the up-pipes.

ATS 2049004248 Pulse Flow Exhaust Manifolds 6685 45.00 ATS 2049004248 Pulse Flow Exhaust Manifolds
$ 986.39
The ATS 2049004248 Pulse Flow Exhaust Manifold for the 2001-2004 GM 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 they're 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. Features: 26% Increased Airflow Durable Cast Design Improved Spool-Up Increased Throttle Response Note: This manifold set is intended for use on Non-EGR applications.
BD-Power 1041460 Full Bore Exhaust Manifold 842 12.00 BD-Power 1041460 Full Bore Exhaust Manifold
4.5 5 10
$ 165
The BD-Power 1041460 Full Bore Exhaust Manifold will restore the balance to your engines exhaust flow, reduce cylinder load and reduce exhaust gas temperatures. The factory driver side exhaust manifold in your 01-10 Duramax is pinched down to allow for steering shaft clearance that isn't even required! As a result, your exhaust flow is significantly disrupted. The BD-Power Full Bore Exhaust Manifold addresses this issue by maintaining internal bore size. Made from high-silicon ductile iron, the Full Bore is a direct, bolt-in replacement for the factory manifold and is even drilled and tapped to accept the most popular EGT probes. Stock Exhaust Manifold: Only flows 80% of the passenger side manifold 3 cylinders only operate at 80% capacity and load others down No access to measure exhaust temperature BD-Power Exhaust Manfilold: Contaings Exhaust Temperature Probe Port Maintains consistent exhaust pressure and temperature on both sides of the engine Flow matches the passenger side manifold and balances the engines exhaust pressure. Manifold gaskets not included. Additional InformationInstall Sheet
BD-Power 1043800 Up-Pipe Kit 27920 12.00 BD-Power 1043800 Up-Pipe Kit
5 5 1
$ 495
The BD-Power 1043800 Up-Pipe Kit increases both performance and reliability in your 2001-2004 GM 6.6L Duramax. Built from 304 stainless steel, these Up-Pipes feature precision cast mounting flanges that eliminate exhaust tubing blowouts. The 304 stainless tubing also prevents loss of heat energy and does not corrode like aluminized steel or 409 stainless. The larger bore (1.8" ID) internally shielded 304 stainless steel bellows eliminate the restrictive 1.3" OE bellows maximizing exhaust energy to drive your turbocharger. Aftermarket downpipe required. Features: 304 Stainless Steel Construction Increased Turbo Response With Lower EGT's Smooth Mandrel Bends Improves Exhaust Gas Flow Installation Notes: Requires Aftermarket downpipe, will not work with OE downpipe (not included). Due to clearance issues, downpipe must be modified, or "clearanced" for proper fitment with up-pipes. Intended for use on BD and factory GM manifolds.
