Stainless Marine Manifolds & Exhaust Systems
Industry wide, Stainless Marine exhaust systems are recognized for increased horsepower, remarkable weight savings, an exclusive five-year warranty and an incredible value. Tests by both Hot Boat and Trailer Boat Magazines revealed increases of 3.2 to 6.5 MPH on MerCruiser Big Block powered 22'-24' boats
The unique construction results in the heaviest manifold weighing only 23 pounds. A huge savings compared to cast iron. Stainless Marine is one of the top quality and least expensive systems available today. Note: All systems based on Bravo applications.
