From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure.

From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.\u003c\/p\u003e\n\u003cp\u003eReplacing or upgrading your exhaust header is necessary for both engine performance and sound.

On a naturally aspirated 5.7L Hemi, this design can support sharper throttle response, smoother exhaust movement, a deeper exhaust tone and better pull through the upper rpm range.\u003c\/p\u003e\n\n\u003cp\u003eThe short tube version provides the more restrained change and is suited to owners focused on replacing the manifold-area assembly. The Ram 1500 long tube headers use longer 1.75-inch primary tubes and a 3-inch collector for builds focused on stronger exhaust flow and a more aggressive sound.\u003c\/p\u003e\n\n\u003cp\u003eActual output depends on the header style, engine condition, complete exhaust configuration, calibration and installation quality.

An exhaust-leak tick can be louder when the engine is cold and may become quieter as the metal warms and expands.\u003c\/p\u003e\n\n\u003cp\u003eReplacing the manifold assembly can address a leak located in that area. Headers will not repair an internal lifter, camshaft or valvetrain fault, so identify the source of the sound before ordering parts.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation and Exhaust-System Planning\u003c\/h3\u003e\n\n\u003cp\u003eAllow the engine and exhaust to cool completely before installation. Inspect the cylinder-head sealing surfaces, fasteners and nearby wiring before fitting the headers. Follow the correct tightening sequence and torque procedure, then inspect the joints again after the first complete heat cycles.\u003c\/p\u003e\n\n\u003cp\u003eThe long tube version requires more installation planning than the short tube version. Check the outlet connection, Y-pipe or mid-pipe layout, oxygen-sensor routing and existing exhaust modifications before work begins.

From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.\u003c\/p\u003e\n\u003cp\u003eReplacing or upgrading your exhaust header is necessary for both engine performance and sound. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound. FLASHARK offers many products to help you create your own custom engine headers.
