Detroit Diesel 4-71 and 8V-71 Exhaust Manifold 

Direct replacement water cooled exhaust manifold to fit the 4 and 8V cylinder 71 and early style 92 Series Detroit Diesel.

Engine application: Detroit Diesel 4/71 and 8V/71 (will fit early 92 series, call Barr).

Fits Detroit Diesel 3-71, 6V-71, 4-71, 8V-71, 6-71 and 12V-71, all models (direct replacement).

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.

• Barr Marine extends a 1 year warranty on these exhaust manifolds.
• Detroit 71 series exhaust will fit some of the earlier 92 series engines. Please call for assistance.
