When choosing new manifolds, it is recommended to also choose the appropriate new risers / elbows. Although Manifolds such as Barr, Osco and others, including original equipment, often look alike they may not be compatible. It is best to buy manifolds and risers as sets and be sure to include the appropriate riser / elbow. These steps will help ensure compatibility and reliable operation of your marine engines exhaust system for years to come.
