    The exhaust manifold collects exhaust gas from the cylinder head exhaust ports and channels it to a single outlet, connected to an exhaust pipe. The exhaust continues flowing through pipes in the system, through the catalytic converter and muffler, and out the tailpipe. The manifold is secured to the cylinder head and exhaust pipe with bolts or studs and nuts, and these junctures are sealed with gaskets. Exhaust manifolds are generally durable, but if your vehicle needs repair, you can count on our replacements to look, fit, and function just like original equipment, but for much less cash.

    Most exhaust manifolds are cast iron, however some are constructed from steel or stainless steel tubes welded together and to a flange that attaches to the cylinder head. Heat shields are mounted on some manifolds to protect other components from their extreme heat, and on some applications to prevent exposing the cabin floor to excessive heat, which could make driving very uncomfortable. On some vehicles the catalytic converter is integral with the manifold, and some manifolds have a port for the oxygen sensor, which signals the exhaust oxygen content to the engine control module.

    In-line 4-cylinder and 6-cylinder engines typically have one exhaust manifold, while V6 and V8 engines have two, one for each cylinder bank. The exhaust pipe that connects to the manifolds on V-type engines is called a Y-pipe, but some engines have a manifold crossover pipe that connects the manifolds, and only one exhaust pipe that exits from one manifold. Exhaust manifolds are generally one of the most reliable components in the exhaust system, but because they continually experience thermal stress, along with other factors, occasionally replacement becomes necessary.

    Thermal stress is caused by the tremendous difference between cold and normal operating temperatures that occur over thousands of heating and cooling cycles. Due to this stress manifold cracks and/or warpage can develop, resulting in an exhaust leak and noise. With a leak there is the potential for noxious exhaust fumes to enter the cabin, and the hot escaping exhaust can also burn and damage adjacent components like wires and hoses. A warped manifold may not seal against the cylinder head properly, which could also result in an exhaust leak and noise. Rust is a common problem with cast iron manifolds and this can result in seized and broken studs, and corroded surfaces that may no longer seal properly. It’s also common for heat shields to crack and cause a rattling noise.

    Regardless of the exhaust manifold malady, we can help with OE quality replacement components. We have exhaust manifolds, exhaust manifolds with integrated catalytic converters, manifold and exhaust pipe gaskets, studs/nuts, bolts, crossover pipes, and everything else exhaust manifold related. Many of our manifolds and manifolds with integrated converters come as complete kits with all gaskets, hardware, and shields (as required) included, so one part number gets you everything you need to complete the job. And in addition to replacement units for late model vehicles we also offer reproduction exhaust manifolds for many classic and muscle cars, along with heat shrouds, heat risers, mounting bolts, and bolt locks. These parts are made by restoration specialists and correct in every detail.
