Back Pressure

Back Pressure at the exhaust ports occurs when the catalytic converter and muffler of a standard exhaust system refuse to accept the outflow of gases. This back pressure is being pushed against by each piston; therefore the engine power out exhaust stroke is reduced. Consequently, the pressure has to be maintained in a lowest level so that it will avoid tight bends in the pipe work. A chamber called manifold is where all cylinders pump their exhaust gases into and this applies to a standard engine. Once the manifold is being designed inadequately, the following cylinder will have a back pressure being created as the output of the cylinder. For a progression of the performance, a header together with a collector system is the recommended ones to use instead of a manifold. For a header, it has pipes which direct from each of the ports connecting to a collector where there are individual pipes that easily led into a single pipe. The pipes are designed and shaped in such lengths, and this will allow more spacing for the pulses of gas from the cylinders avoiding roughly and uneven peaks of pressure.
