    Exhaust Header VS Manifold, which is the better choice?

    The structural differences between exhaust headers and manifolds are the material and size. 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.

    I gave them a four only because they didn't come with mounting hardware.

    I' m sorry for the inconvenience, the cause of this problem may be lost in the transportation of the logistics provider, please contact our customer service e-mail, the staff will arrange for your replacement.

    Short Headers 2010 F150 5.4L

    I bought the short headers for the 5.4L Ford and they are great so far. The header gaskets are thrown in the box with no cardboard or wrapping so they were destroyed. I used the Fel Pros and had no issues. The flange bolts provided are way too short. You need 2.5 to 3 inch bolts at least. Otherwise they are well built and sound good. Really impressed for $150 headers.
