Upgrade the exhaust system on your boat with Schoenfeld marine headers. These quality-built, over-the-transom headers will free-up horsepower and improve throttle response. Replace your restrictive factory manifolds with Shoenfeld marine headers and tear up the lake. They're available in a variety of styles and sizes for countless year/make and engine applications. (Special warning regarding Schoenfeld painted headers only. The paint on these headers is not designed as a final finish; it is designed to protect the headers after the manufacturing process and during shipping. This paint will not withstand the high-heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high-heat paint or coating designed for use on headers be applied.)
