Sierra 18-2849-1  About H20 Performance Parts    H2O has been a private label manufacturer of aftermarket exhaust manifolds, risers, elbows and spacers for the marine industry since 2010. In 2013 we launched our own brand, H20 Performance Parts, as an additional avenue to provide high-quality marine exhaust components at a cost-effective price. By combining the latest tooling and an innovative casting procedure, H2O manifolds are produced with uniform wall and water jacket thicknesses; resulting in exacting fit and performance while eliminating traditional leak points. The material used for each casting is a high-grade cast iron that is continually tested to ensure a consistent mix and melt and to provide structural integrity and strength. Every mounting surface on every manifold, riser and spacer are CNC machined to guarantee an excellent gasket mating surface. Every component is 100% leak tested and coated with a baked enamel surface before leaving our manufacturing facility to provide a high-quality product that looks as good as it performs.
