AFE Exhaust Manifold

An exhaust manifold is a system which is used to vent exhaust gases away from an engine. The manifold extends from the cylinders to the exhaust pipe, collecting and moving exhaust away from the engine. The function of this exhaust system component may not be complex, but each vehicle would definitely not perform properly without them. Exhaust manifolds are a network of passages that routes the exhaust gases from the various exhaust ports toward the mufflers and catalysts of the exhaust system. ...More

AFE Exhaust Manifolds - More Info

Eliminate the costly exhaust manifold cracks prevalent in the factory exhaust manifold. The aFe Bladerunner exhaust manifold for the popular 5.9L Dodge Cummins sets the new standard. Constructed out of cast 304 stainless steel with a reinforcing rib for strength along the flange and ultra-thick wall flange at the port. The Bladerunner exhaust manifold outflowed the factory exhaust by 23% improving exhaust flow, performance and throttle response. This manifold also features 2 EGT probe ports, thick wall design for increased strength (0.25" vs 0.15" for the stock unit), matched ports and has a merged runner design to maximize maximize exhaust flow. Once to install this awesome exhaust manifold, anyone will feel improved turbo spool up times, improved throttle response and performance.

The number and design of the exhaust manifolds depend on the cylinder heads to which they are attached for efficiency in gathering exhausts from each of the individual exhaust ports. Exhaust can be harmful to inhale, making it very important to have a fully functional exhaust manifold; because it can sometimes be difficult to detect an exhaust leak, people may inhale exhaust gases without being aware of it. When the pistons in the engine reach the exhaust stroke, they push the exhaust fumes up into the exhaust manifold. The manifold consists of a series of pipes which connect to the cylinders and then consolidate in a central large pipe which vents to the exhaust pipe. A series of gaskets are used to create tight seals so that exhaust cannot escape from the cylinders.
