Now that we have a better understanding of why headers work, the question now becomes do they work in the presence of boost? To find out, we decided to run a series of tests by comparing headers ...

We often try our best to get the most performance possible from our engines. In the search for more power, we often remove exhaust manifolds and swap them out for a set of headers. Available in ...

While it is very common to port match an intake manifold to a set of cylinder heads to ensure that there is proper port alignment so that the air /fuel mixture can enter the intake side of the head ...

An exhaust manifold or header collects the exhaust gases from multiple cylinders into one pipe. Usually constructed of cast iron, the exhaust manifold is a pipe that conducts the exhaust gases from ...
