An integrated Exhaust Manifold, or "headifold," is an exhaust manifold cast into an engine's cylinder head and cooled by antifreeze. This type of design, where the exhaust manifold is no longer a ...

The engines that power the vehicles we drive are exceptional machines. They're capable of generating insane amounts of power in a relatively confined space, and they can generally be expected to ...

Only a few things are so aggravating that I would rather let my Corvettesit in the garage than drive it until it's repaired. Exhaust leaks areat the top of the list. Repairing exhaust leaks requires ...

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 ...

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 ...
