Peace of mind and power to spare! Barr Manifolds are designed to reduce back-pressure and often when replacing OEM-installed manifolds, more horsepower is achieved.

When choosing a Manifold, 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, it is recommended to buy manifolds and risers as sets. Where applicable, buy replacement manifolds in pairs and be sure to include the appropriate riser / elbow.(more...)
