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.
