Barr Marine castings have a thicker interior wall, are painted to match original manufacturer colors and are packed in foam for added protection during shipping and storage. Barr manifolds and exhaust connectors are designed to minimize back pressure, and in many cases more r.p.m.'s are achieved after replacing an OEM manifold with Barr replacement parts.
3 year limited warranty on Barr exhaust manifolds, risers and exhaust connectors (1 year when used for commercial purposes).
