Marine Exhaust Manifolds, Headers, Tailpipes, Risers and Accessories

We've built this guide to help you get a little more information on the parts we offer by organizing the information in an easy to use web guide. Exhaust systems are an important part of your marine engine. Typically, Marine Exhaust manifolds and headers are the last stop for the cooling water running through your engine before it is dumped overboard. The exceptions to this are dry tailpipes and closed cooling engines. Basic Marine Exhaust is typically made out of cast iron. Cast iron is very heavy and it is not used in any kind of performance exhaust. Cast aluminum manifolds are typically the first level of performance exhaust. Much lighter than iron, the weight savings alone helps performance. Most aluminum manifolds are cast with individual exhaust runners to improve performance, many cast aluminum systems are paired with stainless steel risers and tailpipes for ever better performance. The best hi-performance exhaust comes in the form of Stainless Steel Header systems. These tubular header systems are the top of the line technology when it comes to getting the most out of your boat.
