Exhaust Manifold – Steel or Cast Iron?

A few months back I had written an article about ceramic coatings being used on diesel engine parts like exhaust manifolds, exhaust pipes and some cases cylinder heads. The benefits of ceramic coatings were also discussed, especially when used on parts that are subject to extreme heat. I had ended the article mentioning that DIY options are tempting, but for more longevity of your parts, having them done professionally is the best way to go.

Noticing Exhaust Manifold Problems

When was the last time that you checked your exhaust manifold? Was it when you last had an exhaust leak? Exhaust manifolds are the ‘leading role’ of your engines exhaust system, yet when there is an exhaust leak they are not the first thing to be checked. The exhaust system itself has many parts, some are very complex. The manifold is simple in design and function. They connect to the cylinder head and funnel hot exhaust fumes into one simple exhaust pipe. An exhaust leak can be due to a blown exhaust gasket, which is a relatively inexpensive fix, if caught soon enough. Leaks can also come from cracks in the manifold itself.

Exhaust Gases & Emission Reduction

Usually made from cast iron or stainless steel, an exhaust manifold collects engine exhaust fumes from multiple cylinders, (fumes made during the combustion process) and delivers them to the exhaust pipe. The exhaust pipe in turn, funnels the exhaust gases to a catalytic converter and the muffler.
